Professional Applications & Engineering Value
These 8-32 UNC thread forming screws are engineered to solve common fastening challenges in metalworking and assembly. The zinc-plated steel material resists rust and corrosion, ideal for applications in steel, aluminum, brass, cast iron, and sheet metal. The thread forming (SW type) design displaces material to create strong, permanent internal threads without chips, reducing the risk of loosening under vibration. Combined with an external hex drive and flanged head, they provide quick, tool-friendly installation and enhanced clamping force, making them perfect for automotive, machinery, and electrical enclosures where reliability is critical.
Specification Summary & Compliance
This screw features a No. 8-32 UNC coarse thread with a diameter of 0.164" and full threading over its 1/2" length. It conforms to standard thread forming (SW) specifications and is designed for use with a No. 26 drill bit (0.146" diameter). The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted substances and suitable for industrial and export applications.
