Service Hotlinechurchill cityT-bolts have been widely used in the fields of aviation, aerospace and defense due to their good positioning and anti-shedding effects. Its related standards have special requirements for accurate positioning, anti-falling off, and dimensional consistency of churchill cityT-bolts. This requires that the position, size and shape and position tolerance of the anti-fall hole of the T-bolt shank must be controlled within a certain range. Therefore, the processing method of the anti-shedding hole is particularly important. Since the machined anti-shedding hole is located at the position of the rod, the milling processing efficiency is too low, the product cost is high, and there is a large machining error. When conventional drilling is used, the consistency of the anti-shedding hole size cannot be guaranteed. To solve the above problems of low efficiency and dimensional instability
The safety of screws and bolts in important occasions is related to the safety of the overall operation of the equipment, especially in public places and open air places, the theft of screws will cause major safety hazards. It is easy to loosen, and there is a safety hazard in long-term use.
screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step.

Before the special vehicle is refitted, the chassis and the car frame should be reinforced again, and the fastened part of the rivets should be disassembled before the car frame is reinforced.
In the current plastic matrix, it is common to use self-tapping screws or add copper inserts during injection molding. The former has poor strength, and the threaded hole is easy to crack; the processing cost is high, the injection molding efficiency is low, the labor cost and manufacturing cost are increased, and the insert is easy to slip and crack on the plastic, and the thread strength of the copper insert is not as high as that of the iron nut.
