Professional Applications & Engineering Value

These 410 Stainless Steel flanged hex head tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The external hex drive provides superior torque transmission compared to other drive types, ensuring consistent seating and clamp force. The integrated flange design replaces the need for separate washers, streamlining inventory and installation while providing excellent bearing surface distribution. These self-tapping screws are engineered specifically for sheet metal applications where material thickness constraints (up to 0.025") require precision fastening solutions without compromising structural integrity.

Specification Summary & Compliance

This No. 10-12 x 1-1/2" tapping screw features a 0.19" thread diameter with 12 threads per inch and fully threaded pointed tip configuration. The screw meets standard thread forming (A/AB) specifications for sheet metal applications and requires a No. 21 drill bit (0.159" diameter) for proper installation. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety for industrial use.
