Service HotlineIron two combination screws can be sucked up with magnets, but stainless steel two combination screws are difficult to be sucked up. Environmentally friendly three-combination screws and non-environmentally friendly ones are invisible to the naked eye and require mechanical testing. It cannot be judged with the naked eye and out of thin air. The specifications of the two combination screws need to be determined by the national standard. The salt spray of the two combination screws needs to be measured with a salt spray machine for how many hours.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (10), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the deformation. effect.
A rivet is a part that uses its own deformation or interference to connect the riveted parts in riveting. With the continuous progress and development of science, rivets have been used in many occasions because of their convenient use and reliable connection. The rivet includes a nail head and a stem. The traditional processing mold for the rivet head includes a base, and a nail head forming part is arranged on the base. However, due to the limited service life of the mold, the processing mold of this structure is replaced. It needs to be replaced together with the base, which is a waste of material, which increases the production cost, and the rivet itself is relatively cheap, so this reduces the profit of the enterprise.
Aiming at the shortcomings of the above-mentioned cabinets in the prior art that are assembled through hardware accessories, which affects the overall appearance, Yueluo provides a cabinet with a hidden screw-type installation structure and an assembling method thereof. The plate is fixed so that the screws can be hidden from the outside.
GB6177 Hexagon Flange Nuts - Grade GB55 Hexagon Thick Nuts GB56 Hexagon Extra Thick Nuts GB1229 Large Hexagon Nuts (High Strength for Steel Structure) Lock Nuts Other Names: Root Nuts, Lock Nuts, and Nuts. Purpose: To lock the outer joint of the through wire or other pipe fittings. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: Torx hand screw screws, hand percussion rivets, copper rivets, national standard color metal flat washers, external hexagon implosion screws and other products, We can provide you with the right fastener solution for you.
