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 typically used for fastening light metal sheets, wood, and plastic. They are manufactured with case hardened carbon steel and are finished with a zinc plating for enhanced durability. The screws comply with the ASME B18.3 standards, which outline the general requirements for their dimensions and performance.
