Summary of information:We have more than ten years of experience in screw industry production. The main products are: galvanized/nickel-plated ...

The DISC-LOCK lock nut is composed of two parts, each part has staggered cams. Due to the internal wedge design, the slope angle is greater than the nut angle of the bolt, the combination will be tightly bite into a whole, when vibration occurs. When the DISC-LOCK lock nut is staggered, the raised parts of the DISC-LOCK lock nut move with each other to generate lifting tension, so as to achieve a perfect anti-loosening effect.

An embodiment of Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw slotting device, as shown in Figure 1, which includes a workbench 1, a vibrating plate 2 is arranged on the upper part of the workbench 1, and a conveying device 3 is arranged on the vibrating plate 2. Below the discharge port, the slotting device 4 is arranged on one side of the conveying device 3, and the slotting device 4 is provided with a reciprocating cutting wheel 42 that can slot the screws in the conveying device 3 when it extends out. The device 4 is also fixedly provided with a fixed wheel 48 for grinding the grooved screws. Using the screw slotting device, the screws can be automatically sorted by the vibrating plate 2, which improves the production efficiency. The reciprocating motion of the cutting wheel 42 can greatly reduce the probability of knife breakage. Sanding, fixes burrs and roughness.

self-locking nut is a nut that can self-lock by friction. The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (see GB/T3098.9-2002 national standard).

A kind of screw provided by Yueluo, the rod body of the screw rod has a thread segment, and the two ends of the thread segment are respectively provided with annular and two convex rings. The nominal size of the thread segment, and the distance from the convex ring at the rear end of the screw in the screwing direction to the rod core is greater than the nominal size of the thread segment.

For a long time, the rivets used in general riveting, especially the ordinary rivets and bolts and other fasteners commonly used in steel structures such as vehicles and bridges, have low connection reliability, especially under alternating load and impact conditions. Looseness is easy to occur, the maintenance cycle is short, and the maintenance cost is high in the later period, which cannot meet the requirements of railway freight.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: countersunk head cross stainless steel screws, BSO pressure riveting studs, adjusting set screws, ball screws and other products, we can provide you with suitable products for you.
