#12 x 1" Sheet Metal Screws Self Tapping Pan Head Stainless Steel Qty 1000 Sheet metal screws have sharp threads that cut into a material such as sheet metal, plastic or wood. They also make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood. About Self tapping Screws A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill. The screws in this auction are not "Self Drilling" and do require a pilot hole for a thick gauge material General Product Information Head Style : Pan Drive Style : Drive Size : #3 Thread : #12 Length : 1" Material : Stainless Steel 18-8 Quantity of Fasteners in Package : 1000 Detailed Product Information: Head Diameter : 0.425" Head Height :
