Professional Applications & Engineering Value

These thread forming tapping screws are engineered to solve common challenges in sheet metal assembly, where traditional fasteners may strip or require additional tapping steps. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, making these screws suitable for outdoor equipment, HVAC systems, and electronic enclosures. The pan head with No. 3 square drive ensures a flush fit and high torque application, reducing the risk of head damage during installation. By utilizing thread forming technology, these screws displace material to form precise internal threads, enhancing pull-out strength and vibration resistance in thin-gauge metals. This design minimizes the need for threaded inserts or nuts, streamlining production and lowering total assembly costs in industrial construction and metal fabrication projects.

Specification Summary & Compliance

This product features a thread diameter of 0.242" with approximately 10 threads per inch, ensuring consistent engagement in compliant materials. Manufactured to standard inch system dimensions, these screws are fully threaded with a pointed tip for easy insertion. Compliance includes adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances and supporting sustainable procurement practices. The design is optimized for use with a 5.5mm (0.2165") drill bit, achieving a maximum drilling thickness of 0.025" in sheet metal applications.
