Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal applications where reliable, permanent fastening is critical. The 18-8 Stainless Steel composition provides excellent corrosion resistance, making these screws ideal for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture or chemicals. The thread forming technology eliminates the need for pre-tapped holes, creating strong, strip-resistant threads that withstand vibration and thermal cycling. The wide truss head distributes clamping force over a larger area, preventing sheet metal distortion while the No. 3 Phillips drive ensures secure tool engagement during installation. These features combine to deliver reduced assembly time and long-term reliability in demanding industrial environments.

Specification Summary & Compliance

This No. 12 x 1-3/4" tapping screw features a 0.216" thread diameter with 11 threads per inch and requires a 3/16" drill bit for proper installation. Manufactured to A/AB thread forming standards with fully threaded design and right-hand threading. The screw meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability. Maximum drilling thickness of 0.025" ensures optimal performance in standard sheet metal applications.
