Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional engineering value in demanding industrial environments where corrosion resistance is critical. The thread forming design eliminates the need for pre-tapped holes, creating strong, permanent threads in sheet metal applications up to 0.025" thickness. The fully threaded No. 8 configuration ensures maximum holding power across the entire fastener length, while the Phillips oval head provides a clean, finished appearance when countersunk. Engineered for metalworking and fabrication, these screws maintain integrity in marine, chemical, and outdoor applications where ordinary fasteners would fail. The combination of A/AB tapping screw type with precise 15 threads per inch delivers reliable performance in thin-gauge materials without stripping or thread damage.

Specification Summary & Compliance

This inch-system fastener features precise dimensional specifications including 0.164" thread diameter, 15 threads per inch, and standard oval head profile with 82° countersink angle. Manufactured as a thread forming tapping screw type A/AB with right-hand threading and pointed tip for easy starting. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance standards. Designed for use with No. 29 drill bit (0.136" diameter) in sheet metal applications requiring maximum corrosion resistance and reliable fastening performance.
