The post-treatment of nickel-phosphorus plating includes two main processes of driving hydrogen and polishing. ①Hydrogen drive; according to the relevant standards, the hydrogen drive temperature after plating is 200±10℃, and the treatment time is 2h. 200 ℃ is beneficial to eliminate hydrogen embrittlement, relax internal stress, improve the bonding force between the coating and the substrate, and improve the corrosion resistance of the coating. ②Polishing; the polished bolt has a bright appearance, but in order to better improve the quality of the coating, smooth the tiny traces, and obtain a bright mirror-like surface, the coating needs to be polished with a polishing machine.

T-bolts are a common type of bolts that tend to be used with rails when used. When the existing rail is in use, the T-shaped bolts are easily stuck and cannot reach the designated position well, and the use is not convenient enough, so that the T-shaped bolts cannot be well fixed.

Rivets are mostly used for fixed riveting and movable riveting between parts. The rivets used for movable riveting are mostly cylindrical, and there is no size limit for riveted parts, which is easy to cause parts to be squeezed and deformed during riveting. For example, The parts are inserted into the parts for active riveting. When riveting, the riveting force can easily cause the parts to clamp the parts, which in turn causes difficulty in the movement of the parts and the parts, high operating force and noise problems, and the parts are easily damaged.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a low-carbon steel rivet nut fastener, which can be easily fixed on a thin wall without welding, easy to operate, firm riveted, and suitable for single-sided riveting.
