Professional Applications & Engineering Value

This No. 6 x 1-1/2" 316 Stainless Steel Phillips Oval Head Tapping Screw is engineered specifically for sheet metal applications, where corrosion resistance and joint integrity are paramount. The thread forming (Type A/AB) design displaces material to form strong internal threads, eliminating the risk of loose chips that can cause electrical shorts or mechanical interference in assemblies. The use of 316 stainless steel provides exceptional protection against chlorides and industrial chemicals, significantly extending service life in demanding environments like marine, food processing, or architectural metalwork. The combination of a Phillips drive and oval head offers a balance of installation torque and a finished, low-profile appearance, making it a reliable and aesthetically pleasing industrial fastener for critical connections.
