Phillips 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. Phillips Pan Head Sheet Metal Screws make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood. Phillips Pan Head Sheet Metal Screws have a rounded top with an undercut (flat bottom) head. The head of a Pan Head Screw protrudes above the surface being fastened.
Black Oxide Treatment adds corrosion and abrasion resistance to the Stainless Steel used to make Phillips Pan Head Sheet Metal Screws. This process creates a more durable fastener as well as a sleek black finish desired by industries such as cars, motorcycles and gun and knife handles.
