Professional Applications & Engineering Value

These Type A thread forming screws are specifically engineered for sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides exceptional resistance to corrosion and oxidation, making these Phillips flat head tapping screws ideal for HVAC systems, electronic enclosures, and automotive components exposed to harsh conditions. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The standard 82° countersink angle ensures proper seating in prepared holes, preventing surface protrusions and maintaining aerodynamic profiles in sheet metal assemblies. With fully threaded shanks and precise No. 6 screw dimensions, these fasteners deliver consistent performance across production runs, minimizing installation errors and rework in industrial manufacturing environments.

Specification Summary & Compliance

These tapping screws feature precise 0.138" thread diameter with 18 threads per inch and comply with standard Type A thread forming specifications. The flat head design with standard profile ensures proper countersinking in prepared materials. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental safety standards. The screws are optimized for use with No. 32 drill bits (0.116" diameter) and are designed for maximum drilling thickness of 0.025" in sheet metal applications.
