#12 x 2-1/2" Pan Combo Sheet Metal Screw Zinc Plated 100 - Box
Sheet metal screws/tapping screws are threaded fasteners with the unique ability to "tap" their own mating internal thread when driven into preformed holes in metallic and non-metallic materials. Sheet metal screws/tapping screws are high strength, one-piece, one-side-installation fasteners. Because they form or cut their own mating thread, there is unusually good thread fit, which enhances resistance to loosening in service. Sheet metal screws/tapping screws can be disassembled and are generally reusable.
