In the wonderful world of electric tricycles, there is a “little guy” that seems ordinary at first glance, but is actually a super “big shot”. It is the 10-thread U-shaped bolt. This small item is like a peerless master hidden in the marketplace in a movie. Usually, it keeps a low profile, but once it comes to a crucial moment, its function will simply amaze you! Today, let’s have a good chat about this magical 10-thread U-shaped bolt.

I. Functions and Applications
(1) The “Super Adhesive” for the Frame
The frame of an electric tricycle is assembled by “piecing together” a bunch of components. At this time, the 10-thread U-shaped bolt makes a shining appearance. It is like a super enthusiastic “glue master”, plunging into the key connection points of the frame, such as the “meeting place” of the crossbeam and the longitudinal beam. Its just-right 10-thread specification is like a tailor-made “lock and key”. When it cooperates with the nut, it firmly “sticks” these components together, as if shouting: “Everyone stay still. We should unite tightly and make the frame as stable as Mount Tai!” Without this “super adhesive”, when the vehicle runs on those bumpy roads, the frame would probably have been scattered everywhere like building blocks knocked apart by a naughty child. With the 10-thread U-shaped bolt, the frame instantly becomes a solid fortress and can easily “handle” any road condition. It is definitely the “guardian god” of the frame.
(2) The “Loyal Bodyguard” of the Cargo Box
For an electric tricycle used for carrying goods, the cargo box is its “mobile treasure house”. However, if this “treasure house” is not fixed properly, it will become a “naughty troublemaker” during the driving process. Don’t worry. The 10-thread U-shaped bolt immediately transforms into a “loyal bodyguard”, holding the cargo box and the frame tightly, making them “inseparable”. Whether it’s speeding on a smooth road or crawling with difficulty on a rough path, the cargo box has to obediently stay in place, steady and secure. Without this “bodyguard”, the cargo box might be like a wild horse running loose, “going wild” 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 like a “disaster movie” scene. Therefore, the 10-thread U-shaped bolt is the “protector god” of the cargo box and the goods, always safeguarding their safety.
(3) The “Expert in Settling Accessories”
Those 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 “big backer” and is immediately firmly fixed to the vehicle body. No matter how strong the wind or heavy the rain outside is, the awning can be like a brave soldier, sticking to its post and shielding the driver from the wind and rain. Without this “expert in settling accessories”, the accessories would 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 become cross-eyed! If the storage box shakes off and the things inside spill all over the place, that would be extremely embarrassing. So, the 10-thread U-shaped bolt is an indispensable existence for the accessories. Without it, the whole vehicle would be in chaos.

II. Material Characteristics
(1) The “Precision Magician” of the 10-thread Specification
This “10-thread” specification is really amazing. It is like the “precision magician” in the world of U-shaped bolts. When the bolt and the nut “meet”, their cooperation is simply seamless, like a pair of tacit partners with a special bond. During the tightening process, they fit perfectly and are extremely precise. This high-precision cooperation not only makes the connection as firm as the Great Wall of Steel but also enables it to maintain a good condition 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 is simply born to “display its extraordinary abilities” in the complex usage environment of electric tricycles. It is definitely the “reliable figure”.
(2) The “Steel Tough Guy” Made of High-quality Steel
Don’t underestimate the 10-thread U-shaped bolt just because of its small size. It has a heart of a “steel tough guy”. The high-quality steel it uses has an astonishing strength, just like a strongman with superpowers who can easily withstand huge tensile and compressive forces. For the various complex stress situations during the vehicle’s driving process, it’s as easy as scratching an itch for this bolt. 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 “crying out for help” and would be easily defeated. Relying on its own steel body, the 10-thread U-shaped bolt escorts the safe operation of the electric tricycle and is the well-deserved “safety guard”.
(3) The “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 sturdy “protective clothing” for it. Whether it’s a rainy and humid day, a high-humidity environment, or even a “harsh battlefield” like a saline-alkali area, it can calmly deal with it 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 “weaklings”, but the 10-thread U-shaped bolt is still full of energy and vitality. It is like an “invincible cockroach” and also like a “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 cotton-padded jacket” of the vehicle owners.

III. Installation Method
(1) Preparation Work: Grand Preparations before the “Battle”
Before installing the 10-thread U-shaped bolt, it’s just like going to war. You have to get all the “weapons” ready. Tools like wrenches and screwdrivers are essential. They are good helpers for installation, just like a soldier can’t go to war without a gun. At the same time, the installation position also needs to be tidied up properly. There should be no “mischievous elements” such as debris, oil stains, and rust. Otherwise, the 10-thread U-shaped bolt won’t be willing to work properly. It’s just like you wouldn’t want to live in a messy room. So, cleaning the installation position thoroughly is like providing a comfortable “home” for the 10-thread U-shaped bolt, so that it can happily play its role.
(2) Installation Process: “Surprises” at Every Step
Positioning and Placement: The Record of the Cargo Box “Returning to Its Place”: Let’s take the installation of the cargo box as an example. The “big treasure” of the cargo box needs to be carefully placed in the predetermined position on the frame. Just like finding the correct position for a puzzle piece, 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 drunk man, 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, smoothly entering its “battle position” and ready to show its skills.
The Use of Washers: The Great Role of Small Washers: Put washers on both ends of the U-shaped bolt respectively. Don’t underestimate this small washer. It is like an attentive little assistant that can increase the force-bearing area and prevent the connected parts from being “injured by pressure” 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 heavy object 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 “Strength”: 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 a fragile baby. Keep the position of the U-shaped bolt correct and don’t let it “go off track”. Moreover, tighten the nuts on both sides alternately. Just like two people carrying something together, they need to cooperate well, so that the U-shaped bolt can be evenly stressed and achieve the best fastening 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 child and loosen, which is very dangerous.
The Final Inspection: The Inspection after the “Exam”: After the installation is completed, just like checking your test paper after finishing the exam, you have to use a screwdriver to check whether the nuts are tightened firmly. You can gently shake the connected parts to see if there are any signs of looseness. If you 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: Giving the U-shaped Bolt a “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 person, unable to work properly, and there may even be potential safety hazards.
(2) Cleaning and Maintenance: Giving the U-shaped Bolt a “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 “comfortable 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 lively young man, 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.
