Product Details
Sheet metal screws with a combo drive, which includes both slotted and Phillips heads, are versatile fasteners designed with specially hardened spaced threads and sharp points that enable them to tap their own internal threads. These screws are typically used for fastening light metal sheets, wood, and plastic. They are made from case-hardened carbon steel and feature a zinc plating for enhanced durability. The general requirements for the dimensions and performance of these steel sheet metal screws are specified by ASME B18.3.
