Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are engineered to solve common challenges in sheet metal assembly. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, saltwater, and industrial atmospheres, significantly extending the service life of your products. The thread forming (Type A/AB) design displaces material to create robust, strip-resistant threads, eliminating the need for separate tapping operations and reducing the risk of loose fasteners from vibration. This combination of a flat head with a standard profile and a fully threaded shank ensures a secure, flush mount that is critical for applications in HVAC systems, electronic enclosures, and automotive panels where reliability and a clean finish are paramount.
