Professional Applications & Engineering Value

This black oxide 18-8 stainless steel tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming technology creates strong, permanent threads in pre-drilled holes without generating chips, eliminating contamination risks in sensitive equipment. The combination of stainless steel material and protective black oxide finish provides reliable corrosion resistance where moisture or chemical exposure would compromise ordinary fasteners. The Phillips pan head design with No. 2 drive size ensures consistent seating and prevents cam-out during high-torque installation. Engineered specifically for sheet metal applications requiring 0.025" maximum drilling thickness, this fully threaded fastener maintains structural integrity while withstanding vibration and thermal cycling in industrial environments.

Specification Summary & Compliance

This precision tapping screw features a No. 8 thread diameter (0.164") with 15 threads per inch and 3/4" length in right-hand thread direction. Manufactured to exacting standards with fully threaded construction and pointed tip for easy starting. The screw conforms to industry specifications for thread forming (Type A/AB) tapping screws with standard pan head profile (0.322" diameter, 0.115" height). Compliance certifications include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring responsible manufacturing practices and material safety.
