• Secure, vibration-resistant fastening through thread forming technology that creates strong, permanent threads without chip removal
• Optimized for 0.025" maximum drilling thickness in sheet metal applications with precise No. 29 drill bit compatibility
• Quick, efficient installation with Phillips No. 2 drive system and fully threaded pointed tip for easy starting
• Reliable performance in right-hand threading applications with consistent 15 threads per inch and 0.164" diameter
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

These 316 stainless steel Phillips truss head tapping screws deliver exceptional engineering value in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the risk of loose fasteners in vibration-prone environments by creating precise, cold-formed threads that maintain clamping force. The wide truss head profile distributes load over a larger surface area, preventing deformation in thin-gauge materials while the fully threaded design ensures maximum engagement depth. Particularly valuable in HVAC systems, electronic enclosures, and automotive assemblies, these A/AB type screws provide reliable performance without requiring pre-tapped holes, streamlining production processes in industrial manufacturing.

Specification Summary & Compliance

This No. 8 x 1/2" tapping screw features a 0.164" thread diameter with 15 threads per inch in right-hand direction, manufactured to standard thread forming specifications for sheet metal applications. The screw requires a No. 29 drill bit (0.136" diameter) and is designed for maximum 0.025" drilling thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The Phillips drive system provides consistent torque transmission while the rounded truss head offers both functional and aesthetic benefits in finished assemblies.
