Summary of information:We have more than ten years of production experience in the screw industry. The main products are: nylon screws, stainle...

Nuts are very common fasteners. Generally, the torque cannot be limited when the nut is twisted. The degree of tightness of the nut is mostly judged by the worker's experience. In this way, when the nut is over-tightened, it will lead to the destruction of the thread pair, thereby shortening the fastener. The life of the nut may even cause the bolts to be pulled off in severe cases; and the nut is too loosely screwed, which will lead to the problem of insecure fixing.

The fastener with a nut is composed of a polygonal nut and a bolt. The bolt includes an integral screw rod and a screw head. The fastening surfaces of the nut and the screw head are polygonal. There are external threads on the periphery of the screw, and the main point is that the axial three-dimensional shape of the nut and the screw head is an odd-numbered truncated cone, and the odd-numbered angle is an arc angle, and each arc angle corresponds to an elastic surface.

Stainless steel screws usually refer to steel screws that are resistant to corrosion by air, water, acids, alkali salts or other media. Stainless steel screws are generally not easy to rust and durable, and can be used in environmental protection equipment, medical equipment, communication equipment and other fields.

In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 43 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.

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.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: outer hexagonal nylon column, flat head torx bolt, disc nut, bakelite handle handle nut and other products, we can provide you with suitable tightening Firmware Solutions.
