Hex Washer Head self drilling screws are used to fasten metal to metal or metal and other accessories from 0.8mm up to 3.0mm thickness. It has very good tensile strength and high-torque hex head (that can be easily removed) for fast framing and metal work.

Applicable for all drywall systems and other such applications. Other metal-to-metal applications where high torque is required. The self trapping dill point is designed for penetrating into heavy metal.


Hex Head Screws are cap screws with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant screw has somewhat tighter tolerances than a hex bolt for the head height and the shaft length. The nature of the tolerance difference allows an ASME B18.2.1 hex head screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex head screw is designed in.
