Professional Applications & Engineering Value

This No. 10-12 TPI thread forming screw delivers exceptional value in sheet metal applications where vibration resistance and permanent fastening are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to harsh environments. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement than cutting screws, reducing installation time and preventing metal chips in sensitive assemblies. With its 4-inch fully threaded design and 0.19-inch thread diameter, this fastener ensures maximum pull-out strength in thin materials up to 0.025" thickness, solving common challenges of strip-out and loosening in sheet metal fabrication.

Specification Summary & Compliance

This tapping screw features precision right-hand threads with 12 TPI and Class 2A thread tolerance for consistent performance. The fastener meets Type A/AB thread forming standards and is manufactured to exacting specifications for reliable sheet metal fastening. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material traceability. Designed for use with No. 21 drill bits (0.159" diameter), this screw provides optimal performance in materials up to 0.025" maximum drilling thickness.
