Product Details
Sheet metal screws with square drive are a versatile fastener designed with specially hardened spaced threads and sharp points, enabling them to tap their own internal threads. They are typically used for fastening light metal sheets, wood, and plastic. Constructed from case hardened carbon steel and finished with a zinc plating, these screws meet the specifications outlined in ASME B18.3, which covers the general requirements for the dimensions and performance of steel sheet metal screws.
