Product Details
Sheet metal screws with square drive are a versatile fastener featuring specially hardened spaced threads and sharp points, enabling them to tap their own internal threads. These screws are designed for typical applications such as fastening light metal sheets, wood, and plastic. Manufactured from case-hardened carbon steel and finished with a zinc plating, they meet the standards outlined in ASME B18.3, which covers the general requirements for dimensions and performance of steel sheet metal screws.
