Professional Applications & Engineering Value

This zinc-plated steel tapping screw delivers exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger thread engagement than cutting alternatives. The Phillips pan head design provides reliable drive transfer and sits flush against surfaces, making it ideal for HVAC systems, electrical enclosures, and metal fabrication projects. With full threading along the entire 7/8" length and precise 16 threads per inch configuration, this A/AB type screw ensures maximum pull-out resistance and structural integrity in thin-gauge materials, solving common challenges of strip-out and loosening in dynamic industrial environments.

Specification Summary & Compliance

This precision tapping screw features a No. 7 size with 0.151" thread diameter and 7/8" length, manufactured to exacting dimensional standards for consistent performance. The thread forming design conforms to A/AB tapping screw standards with right-hand orientation and fully threaded shank. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance. Engineered for use with No. 30 drill bits (0.1285" diameter) in materials up to 0.025" thickness, this fastener delivers reliable performance in industrial sheet metal assembly applications.
