Summary of information:We have more than ten years of experience in the production of screw industry, the main products are: Q235 galvanized, l...

self-locking screw comprises a screw main body, a metal screw head is arranged on the upper part of the screw main body, a thread is arranged in the middle part of the screw main body, an interference groove is arranged on both sides of the upper part of the screw main body, and the line of the interference groove is arranged. The included angle is 280-356° with the horizontal line. The bottom of the screw body is provided with an elastic chuck, and the elastic chuck includes an optical axis and a conical head. Guangdong Yueluo Hardware Industry Co., Ltd. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the design of elastic collet, and the screw is provided with threaded segments and interference grooves, so that during the screwing process, the interference groove of the optical axis between the two threaded segments is formed along the screw. The axial elastic force achieves the effect of reliable self-locking, which is easy to use and has high tuning efficiency.

The nuts of some products must be installed on the outside, but due to the small internal space, when the indenter of the riveting machine cannot meet the strength requirements by methods such as riveting and budding, riveting and riveting are impossible. Rivets to be nailed. Applicable to the fixed field of each thickness plate and tube (0.5MM-6MM). Using pneumatic or manual riveting equipment, rivet once and it is easy to secure. Replacement of the existing welding nut to supplement the metal plate, the thin tube welding is easy to melt, and the welding nut is not smooth.

Standards are norms, and each country and sector has its own standards. GB—Chinese National Standard (National Standard) ANSI—American National Standard (American Standard) DIN—German National Standard (German Standard) ASME—American Society of Mechanical Engineers Standard JIS—Japanese National Standard (Japanese Standard) BSW—British National Standard GB—National Standard The standard is one of the many standards in my country, and there are also industry standards, professional standards and department standards. National standards are divided into: GB (mandatory standards) and GB/T (recommended standards) and GBn (national internal standards) and so on. We usually see GB30, GB5783, etc. are mandatory standards. In addition to some basic dimensions such as head-to-side, head thickness, etc., the above standards are mainly different in the threaded part. The threads of GB, DIN, JIS, etc. are all in MM (millimeters), which are collectively referred to as metric threads. Another thread like ANSI, ASME, etc. is called American standard thread in inches. In addition to metric threads and American threads, there is also a BSW-imperial standard, whose threads are also in inches, commonly known as Wyeth threads. In the usual domestic sales business, the most common standards we encounter are GB (National Standard) and DIN (German Standard). In terms of production products, the following standards are mainly encountered: GB30; GB5783; GB5782; GB52; GB6170; GB818; GB819; GB845; GB846; GB70; DIN912; DIN933; DIN931 and so on. GB30 (old national standard) has been replaced by GB5783 (new national standard) in the standard book. GB52 (old national standard) has been replaced by GB6170 (new national standard) in the standard book.

The technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the deficiencies of the existing rivets. The purpose of this utility model is to provide a special rivet for railway freight cars, which can be reused and increase the safety factor. , to limit the movement of the collar in the circumferential direction.

However, although the existing screw can meet the function of connecting and tightening objects, its structure includes a head and a threaded rod connected with the head. Since it only has one threaded rod, it does not have a two-way connection function and cannot be satisfied with the Some special use requirements bring inconvenience to use.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: cylindrical positioning pins, GB867 stainless steel rivets, pressed willow CLS, round cup screws with pads and other products, we can provide you with suitable fasteners for you solution.
