• Precision threading with 15 TPI and 0.164" diameter ensuring consistent, reliable fastening performance
• Optimized for sheet metal applications with pointed tip for easy penetration and maximum drilling thickness of 0.025"
• Full compliance assurance meeting RoHS 3 and REACH environmental regulations for global market acceptance

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming tapping method eliminates common issues with traditional tapping screws by creating stronger, more durable threads through material displacement rather than cutting. This results in improved vibration resistance and reduced loosening in dynamic applications. The combination of external hex drive and flanged design provides superior clamping force while speeding up installation in high-volume production environments. Engineered specifically for sheet metal fastening, these screws maintain structural integrity even in thin materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive components where reliability is critical.

Specification Summary & Compliance

This No. 8 x 5/8" tapping screw features precision right-hand threading with 0.164" thread diameter and 15 TPI specification, manufactured to A/AB tapping screw type standards. The fully threaded design ensures maximum holding power along the entire shank length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. The screw is optimized for use with No. 29 drill bit (0.136" diameter) and is designed for sheet metal applications requiring reliable, high-performance fastening solutions.
