Flat Head Torx & Cross Recess Clinch Set Screw

Product Overview

Flat head clinch set screw is a special sheet metal fastener designed for flush surface installation. Two drive types, Torx recess and cross recess, are optional for different assembly tools. After being pressed into thin metal plates, the entire head is completely flush with the plate surface, without any protruding parts to block shell matching, greatly improving product appearance and assembly safety.

Product Advantages
