8G CSK SQ Stainless Self Tapping Screw

Our 8G Countersunk Square Drive Stainless Self Tapping Screws are designed for a flush, neat finish while delivering strong, reliable fastening. The countersunk head sits flush with the surface, making them perfect for visible work where a smooth, professional look is required.
