Product Details
Sheet metal screws with a combo drive, featuring 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. Constructed from case-hardened carbon steel, they are finished with a zinc plating for enhanced durability. The general requirements for the dimensions and performance of these steel sheet metal screws are governed by ASME B18.3 standards.
