A sheet metal part is a product processed by a sheet metal process, that is, a sheet metal substrate is formed into a sheet metal part with a certain shape through cutting, bending, drilling, welding and other processes. On some sheet metal parts, such as chassis and electrical boxes produced by sheet metal, it is usually necessary to set rivet standoffs to facilitate the installation of internal components. The existing standoffs are usually installed on the sheet metal substrate by extrusion, and the connection is not firm.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a cement screw that is easy to install and can be removed in view of the shortcomings of the above-mentioned cement nails that cannot be disassembled and the expansion screws are not easy to install for the first time.
