In the wonderful world of electric tricycles, there is a unconspicuous but highly skilled “little character”, which is the 10-thread U-shaped bolt. It is like a peerless master who lives in seclusion in the mountains in a martial arts novel. It is silent on weekdays, but once it appears, its function will leave you stunned! Today, let’s have a good chat about this “unsung hero” in the electric tricycle industry.

I. Functions and Applications
(1) The “Steady Housekeeper” of the Frame
The frame of an electric tricycle is pieced together from many components, just like a complex积木castle. At this time, the 10-thread U-shaped bolt is like an overly enthusiastic “housekeeper”, plunging into the key connection parts of the frame, such as the junction of the crossbeam and the longitudinal beam. Its precise 10-thread specification is like a “golden partner” specially created for the frame. It fits perfectly with the nut, tightly “binding” all the components together, as if shouting: “Stay put and make the frame as solid as a rock!” Without this “housekeeper”, when the vehicle is driving on those bumpy roads, the frame would probably have been in pieces long ago, like a积木castle hit by an earthquake. With the 10-thread U-shaped bolt, the frame instantly becomes an extremely solid fortress, which can easily handle any road condition. It is definitely the “guardian god” of the frame.
(2) The “Loyal Chief Guard” of the Cargo Box
For an electric tricycle used for carrying goods, the cargo box can be regarded as its “mobile small treasury”. However, if this “small treasury” is not fixed firmly, it will become a “naughty troublemaker” during the journey. Don’t panic. The 10-thread U-shaped bolt immediately transforms into the “loyal chief guard”, hugging the cargo box and the frame tightly, making them “as close as conjoined twins”. Whether it is speeding on a smooth road or moving forward with difficulty on a rough path, the cargo box has to obediently stay in place, steady and secure. Without this “chief guard”, the cargo box may be like a wild horse running loose, “going wild” wantonly during the driving process, tilting to the left and then to the right, and the goods on the vehicle will also suffer. The scene is simply a “disaster farce”. Therefore, the 10-thread U-shaped bolt is undoubtedly the “protector god” of the cargo box and the goods, always safeguarding their safety.
(3) The “General Director of Settling Accessories”
All kinds of accessories of the electric tricycle, such as rearview mirrors, awning brackets, storage boxes, etc., all rely on the 10-thread U-shaped bolt to help them “settle down”. Take the awning bracket as an example. As soon as the 10-thread U-shaped bolt appears, the awning bracket is like finding a “solid backer” and is immediately firmly fixed to the vehicle body. No matter how strong the wind is blowing or how heavy the rain is falling outside, the awning can be like a fearless soldier, sticking to its post and shielding the driver from the wind and rain. Without this “general director of settling accessories”, the accessories will be like headless flies, wandering around aimlessly and unable to work properly. If the rearview mirror keeps shaking, how can the driver see the road? Maybe they’ll even be dazzled by the shaking. If the storage box shakes off and the things inside are spilled all over the place, it will be extremely embarrassing. So, the 10-thread U-shaped bolt is an absolutely indispensable existence for the accessories. Without it, the whole vehicle will fall into chaos.

II. Material Characteristics
(1) The “Precision Artist” of the 10-thread Specification
This “10-thread” specification is simply as magical as magic. It is like the “precision artist” in the world of U-shaped bolts. When the bolt and the nut “encounter”, their cooperation is as tacit as that of twin brothers with a special connection. During the tightening process, they fit perfectly, and the precision is amazing. This high-precision cooperation not only makes the connection as firm as a wall of copper and iron, but also enables it to maintain a perfect state even after multiple disassembly and installation operations, and there will be no such “let-down” situation as the thread slipping. This 10-thread U-shaped bolt seems to be born to “show its great ambition” in the complex and changeable usage environment of electric tricycles. It is definitely the “reliable figure”.
(2) The “Steel Strongman” Made of High-quality Steel
Don’t look down on the 10-thread U-shaped bolt just because of its small size. It has a heart as tough as that of a “steel strongman”. The high-quality steel it uses has an unimaginably high strength, just like the Hulk with superpowers, which can easily withstand huge tensile and compressive forces. For the various complex stress situations during the vehicle’s driving process, it is as easy as a gentle breeze blowing on its face. No matter how much it bumps or jolts, it can remain as stable as Mount Tai and will never deform or break. If it were made of those fragile materials, they would probably have been “wailing and crying” and would be easily defeated. Relying on its own hard steel body, the 10-thread U-shaped bolt escorts the safe operation of the electric tricycle and is the well-deserved “safety vanguard”.
(3) The “Little Waterproof Superman” with Anti-rust Treatment
In order to “fight” in various harsh environments, the 10-thread U-shaped bolt has also mastered a set of “waterproof magic skills”, that is, it has undergone anti-rust treatment. Common methods such as galvanizing and chrome plating are like putting on layer after layer of indestructible “protective clothing” for it. Whether it is a rainy and humid day, a high-humidity environment, or even a “harsh battlefield” like a saline-alkali area, it can remain calm and composed, and is not afraid of rust and corrosion at all. Other bolts in such an environment may already be covered with rust and have become “weak and vulnerable little creatures”, but the 10-thread U-shaped bolt is still full of energy and vitality. It is like an “invincible cockroach” and also like a “little waterproof superman” with invincible defense. It greatly extends its own service life, saving the vehicle owners both worry and effort. It is simply the “intimate little treasure” of the vehicle owners.

III. Installation Method
(1) Preparation Work: General Mobilization before the “Battle”
Before installing the 10-thread U-shaped bolt, it is just like going to the battlefield, and we have to get all the “weapons” ready. Tools such as wrenches and screwdrivers are essential. They are the capable assistants for installation, just like a soldier cannot go to the battlefield without weapons. At the same time, the installation position also needs to be cleaned up properly. There should be no “mischievous elements” such as debris, oil stains, and rust. Otherwise, the 10-thread U-shaped bolt will not be willing to work properly. This is just like you wouldn’t want to live in a messy room. So, cleaning the installation position clean is to provide a comfortable “home” for the 10-thread U-shaped bolt, so that it can play its role happily.
(2) Installation Process: There is a “Trick” in Every Step
Positioning and Placement: The Great Battle of the Cargo Box “Returning to Its Place”: Taking the installation of the cargo box as an example, this “big treasure” of the cargo box needs to be carefully placed in the predetermined position on the frame, just like finding the correct piece for a complex puzzle. It needs to fit perfectly and be precisely aligned. If this step is not done well, there will be big troubles later. The cargo box will be crooked, looking like a drunken giant, which is not only ugly but also affects its use. Then, align the opening of the 10-thread U-shaped bolt with the parts that need to be connected, such as the installation holes of the frame and the installation ears of the cargo box, and then let the U-shaped bolt pass through the installation holes with a “whoosh”. At this time, the U-shaped bolt is like a brave little soldier charging forward, smoothly entering its own “battle position” and ready to show its skills.
The Use of Washers: Small Washers with Great Energy: Put washers on both ends of the U-shaped bolt respectively. Don’t underestimate this small washer. Its function is amazingly great. It is like an attentive little assistant, which can increase the force-bearing area and prevent the connected parts from being “crushed” when the screw is tightened. Without the washer, when the screw is tightened hard, the connected parts may be marked or even damaged, which is just like a person being hit by a huge stone and will surely be seriously injured. So, although the washer is small, it is an indispensable “little hero” in the installation process.
Tightening the Nuts: The Balance between “Gentleness” and “Toughness”: After screwing on the nuts, first tighten them by hand initially to let the U-shaped bolt “say hello” to the connected parts and fix them preliminarily. Then, use a wrench to slowly tighten the nuts. During the tightening process, be very careful, just like taking care of an extremely fragile baby. Keep the position of the U-shaped bolt correct and don’t let it “go astray”. Moreover, tighten the nuts on both sides alternately. Just like two people lifting a heavy object together, they need to cooperate tacitly, so that the U-shaped bolt can be evenly stressed and achieve the best tightening effect. If only one side is tightened and the other side is loose, it won’t work. Once the vehicle starts running, the U-shaped bolt may be like a naughty and troublesome child and loosen, which is very dangerous.
The Final Inspection: Review after the “Exam”: After the installation is completed, just like carefully checking the test paper after finishing the exam, we have to use a screwdriver to check whether the nuts are tightened firmly. We can gently shake the connected parts to see if there are any signs of looseness. If we find that the nuts are loose, tighten them again immediately. Otherwise, during the vehicle’s driving, if the U-shaped bolt suddenly loosens, it will be like a time bomb exploding, and the consequences will be unimaginable. So, be sure to check carefully and let the 10-thread U-shaped bolt “work” safely and steadily, escorting the safe driving of the vehicle.

IV. Maintenance and Care
(1) Regular Inspection: Give the U-shaped Bolt a “Comprehensive Physical Examination”
It is recommended that everyone give the 10-thread U-shaped bolt a comprehensive “physical examination” regularly, at least once a month. Especially after the vehicle has traveled a long distance, passed through harsh road conditions, or carried heavy loads, it is necessary to check it in a timely manner. At this time, the U-shaped bolt is like a soldier who has just finished a tough battle and may be a little tired and have some minor damages. Through regular inspections, we can promptly find out whether there are any situations such as looseness, deformation, wear, or corrosion, just like a doctor diagnosing a patient, discovering problems in time and treating them promptly. If it is not checked for a long time and the U-shaped bolt has a serious problem, the vehicle will be like a sick giant, unable to work properly, and there may even be potential safety hazards.
(2) Cleaning and Maintenance: Give the U-shaped Bolt a “Refreshing Bath”
It is also very important to keep the surface of the 10-thread U-shaped bolt clean. Regularly wipe it with a clean cloth to remove all the dust, dirt, debris, and possibly attached corrosive substances on the surface, which is just like giving it a “refreshing bath”. For the rusty parts, don’t worry. Gently sand them with sandpaper, just like removing the “dirty scars” on its body, and then apply an appropriate amount of anti-rust oil to put on a “protective coat” for it to prevent the rust from worsening. If the U-shaped bolt is dirty and rusty, it will not only affect its appearance but also reduce its performance, just like a person who is dirty and sick and will surely be listless. So, be sure to take good care of it and keep it in the best condition at all times.
(3) Timely Replacement: Out with the Old, in with the New
Once it is found that the 10-thread U-shaped bolt has serious deformation, breakage, thread slipping, or cannot be tightened, don’t hesitate and quickly replace it with a new “buddy”. Using a faulty U-shaped bolt is like letting a seriously injured athlete continue to compete. It is definitely not okay and may lead to the insecure connection of the vehicle components and cause a safety accident during the driving process. When replacing the U-shaped bolt, pay attention to choosing a product with the same specifications as the original U-shaped bolt and matching materials so that it can fit perfectly and make the vehicle regain its “vitality”. Out with the old, in with the new. After replacing the U-shaped bolt, the vehicle can be like a vigorous horse, running cheerfully again.

The 10-thread U-shaped bolt, this “magical little accessory” of the electric tricycle, has made great contributions to the stable operation and safe driving of the electric tricycle with its unique functions, excellent materials, and convenient installation and maintenance methods. Whether it is for daily travel or cargo transportation, it is silently playing a key role and is an excellent helper that electric tricycle owners should never ignore. Understanding and attaching importance to the relevant knowledge of the 10-thread U-shaped bolt can make your beloved vehicle more reliable and take you on a smooth journey. What are you waiting for?
