Phillips Truss Head Sheet Metal Screws feature an oversized head, with an undercut bottom and a rounded top. Sheet metal screws have sharp cutting threads that cut into sheet metal, plastic or wood. The shanks are threaded up to the head or to the undercut. Truss Sheet metal screws make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood.
Stainless Steel Truss 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 Sheet Metal Screws are used for durable and long lasting applications.
