Professional Applications & Engineering Value

This 316 Stainless Steel Phillips Oval Head Tapping Screw delivers exceptional engineering value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, creating strong, load-bearing threads that resist vibration loosening. The oval head profile with its 82° countersink angle provides a clean, finished appearance while distributing clamping force evenly. Manufactured from premium 316 stainless steel, this fastener maintains performance in marine, chemical, and outdoor environments where ordinary fasteners would degrade. The combination of No. 2 Phillips drive and fully threaded No. 8 design ensures reliable installation and maximum holding power in thin sheet metal assemblies up to 0.025" thickness.
