Professional Applications & Engineering Value

This No. 8-15 thread forming tapping screw is specifically engineered for demanding sheet metal applications where reliability and vibration resistance are critical. The thread forming design displaces material rather than cutting it, creating stronger threads that won't loosen under dynamic loads. The flanged hex head provides excellent torque transmission while distributing clamping force over a wider area, preventing damage to thin sheet materials. With its 0.164" thread diameter and 5/8" length, this screw offers optimal strength-to-size ratio for HVAC systems, electronic enclosures, automotive components, and industrial equipment assemblies. The combination of external hex and slotted drive ensures compatibility with various installation tools, improving assembly efficiency in production environments.

Specification Summary & Compliance

This thread forming tapping screw features a No. 8 size with 15 TPI right-hand threading, fully threaded shank, and requires a No. 29 drill bit (0.136" diameter) for proper installation. The screw meets Type A tapping screw specifications and is manufactured to precise dimensional standards. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial applications across global markets.
