Professional Applications & Engineering Value
This thread forming tapping screw is specifically engineered for demanding sheet metal applications, where its 316 stainless steel composition provides superior resistance to chemicals, saltwater, and industrial atmospheres. The A/AB Type thread forming design displaces material to create strong, chip-free internal threads, eliminating the risk of loose debris that can cause electrical shorts or machinery damage. The combination of a fully threaded shank and a pointed tip ensures easy starting and maximizes thread engagement in materials up to 0.025" thick, delivering reliable performance in HVAC systems, electronic enclosures, and automotive assemblies. Its oval head offers a finished look while the Phillips drive facilitates efficient installation with standard tools.
Specification Summary & Compliance
This screw conforms to standard inch measurements with a No. 6 screw size, 1-1/4" length, and 18 TPI thread pitch. The thread is right-hand direction and fully threaded. It is designed as a thread forming (tapping) screw, Type A/AB, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making it suitable for global industrial supply chains.
