Summary of information:We have more than ten years of production experience in the screw industry. The main products are: DIN582 lifting ring n...

Screw, some people call it screw (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called wood screws; they are the ones with a pointed end at the front and a larger pitch. They are generally used to fasten wooden and plastic parts. The screw rod is a machine screw (machine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts.

A pin and a pin piece inserted on the pin, the width of the pin piece gradually decreases from the insertion end to the other end, and the pin piece is also provided with a protrusion, the protrusion is a triangular ratchet tooth shape, the An insertion hole is arranged on the pin, and a pawl corresponding to the protrusion is arranged in the insertion hole.

hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of an ordinary screw, and the height is 7cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.

met a customer before, and the stainless steel screws needed by the company need to be prevented from loosening. Simply put, the stainless steel screw should be used on the product material so that the stainless steel screw will not fall off lightly. The screws are required to be more tightly connected with the product material. For the solution of stainless steel screw anti-loosening, there are two solutions. Next, the following two solutions to prevent loosening of stainless steel standard parts are presented. The first is to use the resilience of special materials, such as engineering resin materials, which have good resilience. Attach it to the stainless steel screw thread. Make it mechanically rub against the nut, or material product. Generate vibration and absolute resistance. Completely solve the problem of loose screws. The second, simply put, is to apply a layer of glue on the thread of the stainless steel screw, the so-called dispensing. This glue is called drop-resistant glue. This glue has good properties such as high stickiness and non-toxicity. This glue is applied to stainless steel screws, and when dry, it adheres extremely well. The stainless steel screw thread can be combined with the nut thread, or after the product threaded hole is joined, resulting in a super tightening effect. Play a super good anti-loosening effect.

The slotted nut mainly refers to the hexagonal slotted nut, that is, the slot is machined above the hexagonal nut. It is used in conjunction with screw bolts with holes and cotter pins to prevent the relative rotation of the bolts and nuts, see GB6178 ~ 6181 and so on.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: outer hexagon flat top flange bolts, U-shaped screws, 304 cup head socket head cap screws, bolts and nuts, high-strength nuts and other products, we can provide you with Provide the right fastener solution for you.
