• Fully threaded shank provides maximum grip length and uniform stress distribution across the entire fastener
• Pan head profile offers excellent bearing surface for reliable clamping force in sheet metal assemblies
• Optimized for 0.025" maximum drilling thickness with precise No. 32 drill bit compatibility for consistent performance
• Environmental compliance assurance with RoHS 3 and REACH regulations for global market acceptance

Professional Applications & Engineering Value

This Black Oxide 18-8 Stainless Steel tapping screw delivers exceptional engineering value in sheet metal applications where corrosion resistance and installation efficiency are critical. The thread forming design (Type A/AB) eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that withstand dynamic loads. The 18 TPI thread pitch and 0.138" thread diameter provide optimal engagement in thin materials, while the Phillips pan head ensures flush mounting and consistent clamping pressure. These fully threaded screws are engineered to prevent material deformation and maintain joint integrity in HVAC systems, electronic enclosures, and industrial equipment where reliable sheet metal fastening is essential for long-term performance.

Specification Summary & Compliance

This No. 6 x 3/4" tapping screw features precise inch system dimensions with 0.138" thread diameter and 18 TPI thread form meeting standard industrial specifications. The right-hand threaded, fully threaded design ensures consistent performance across the entire 3/4" length. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material transparency. The screw is optimized for use with No. 32 drill bit (0.116" diameter) and engineered for 0.025" maximum drilling thickness in sheet metal applications.
