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. These screws come in many types of heads, pan, flat, truss, oval, etc. Sheet metal screws make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood.
18-8 Stainless Steel Phillips Oval Sheet Metal Screws are used for the material's corrosion and rust resistant properties. Grade 18-8 Stainless Steel is the fastener industry standard.
