• Maximum holding power through thread forming technology, ensuring secure fastening in sheet metal without pre-tapped holes
• Efficient installation with Phillips No. 2 drive, providing reliable torque transfer and reduced cam-out risk
• Full thread engagement along the 5/8" length for consistent grip and vibration resistance in various material thicknesses
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries
• Optimized for 0.025" maximum drilling thickness with recommended No. 21 drill bit, streamlining assembly processes

Professional Applications & Engineering Value

This No. 10-12 x 5/8" Phillips Truss Head tapping screw is engineered to address common challenges in sheet metal fabrication and assembly. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in demanding conditions like outdoor enclosures or humid environments. Its thread forming (A/AB type) design creates strong, permanent threads in ductile materials, eliminating the need for separate tapping operations and reducing installation time. The wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent sheet distortion and improve joint integrity. With a fully threaded shank and right-hand thread, it ensures consistent performance in automated or manual driving applications, making it a reliable choice for HVAC systems, electronic chassis, and industrial machinery where vibration resistance and durability are critical.

Specification Summary & Compliance

This tapping screw features a thread diameter of 0.19" with approximately 12 threads per inch, adhering to standard inch measurements for precise fit. The Class 2A thread tolerance ensures compatibility with typical sheet metal applications, while the pointed tip facilitates easy starting. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe industrial use. Manufactured to meet common industry specifications for thread forming tapping screws, it is designed for reliability in sheet metal fastening with a maximum drilling thickness of 0.025" when used with a No. 21 drill bit (0.159" diameter).
