Professional Applications & Engineering Value

This No. 8-15 x 1-1/4" stainless steel tapping screw delivers exceptional engineering value in sheet metal applications where vibration resistance and material integrity are critical. The thread forming technology eliminates the need for pre-tapped holes, creating stronger threads that won't strip under stress. Made from 18-8 stainless steel, these screws maintain their structural integrity in corrosive environments, making them ideal for outdoor equipment, HVAC systems, and electronic enclosures. The pan head design provides a low-profile finish while the pointed tip ensures precise alignment during installation. With right-hand threading and full threading along the shank, these fasteners distribute load evenly across the entire engagement length, preventing material deformation in thin sheet metal up to 0.025" thickness.

Specification Summary & Compliance

This A/AB type tapping screw features precision Class 2A thread tolerances with a 0.164" thread diameter and 15 threads per inch configuration. The fastener is manufactured to industry standards for thread forming screws with a pointed tip for easy starting. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence. Designed for use with No. 29 drill bits (0.136" diameter), this screw provides reliable performance in sheet metal applications requiring maximum drilling thickness of 0.025".
