Square Drive Pan Head Sheet Metal Screws have sharp cutting threads that cut into sheet metal, plastic or wood. The shanks are threaded up to the undercut of the screw. Square Drive Pan Head Sheet Metal Screws make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood. The head of a Pan Head Screw protrudes above the surface being fastened.
Stainless Steel Pan Head Sheet Metal Screws are industry standard Grade 18-8 Stainless Steel. This material provides corrosion and rust resistance to the screw in fresh water moisture environments. Stainless Steel Square Drive Sheet Metal Screws are used for durable and long lasting applications. The Square Drive is designed to eliminate the stripping effect sometimes experienced with other types of drives, allowing for higher torque installation and less cam out.
