Product Details
Sheet metal screws with square drive are a versatile fastener featuring specially hardened spaced threads and sharp points, designed to tap their own internal threads. These screws are typically used for fastening light metal sheets, wood, and plastic. They are manufactured from case-hardened carbon steel and come finished with zinc plating for added corrosion resistance. The screws comply with ASME B18.3, which outlines the general requirements for their dimensions and performance.
