Professional Applications & Engineering Value

These No. 8 flat head tapping screws are engineered specifically for sheet metal applications where vibration resistance and long-term reliability are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making them ideal for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture or chemicals. The thread forming technology creates stronger, more permanent connections by displacing material rather than removing it, resulting in superior pull-out strength and vibration resistance compared to traditional thread cutting screws. The 82° countersink angle ensures flush mounting in standard sheet metal applications, while the square drive design prevents stripping during high-torque installation. These A/AB type tapping screws deliver consistent performance across various industrial fastening scenarios where durability and reliability are paramount.

Specification Summary & Compliance

These precision-engineered tapping screws feature a 0.164" thread diameter with 15 threads per inch and full threading along the 3" length for maximum engagement. The flat head design with standard profile ensures proper seating in prepared holes. Manufactured to exacting standards with Class 2A thread tolerances for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. Compatible with standard No. 29 drill bits (0.136" diameter) for optimal hole preparation in sheet metal up to 0.025" thickness.
