product features

Hex head self-drilling screws are engineered to be corrosion resistant and come in various sizes and materials. Depending on the size, the applications of the hex self-drilling screws can vary – the smaller screws are used in applications like fixing thin gauge metals and fixing metal to wood. The larger screws are used in roofing and other industries which require self-drilling through tough metals. Our screws come in stainless steel, alloy steel, carbon steel and other materials which prevents corrosion.

If the hex head self-drilling screws are used in extremely hard materials, it is advised to use it after a pilot hole has been drilled. Our screws are case hardened and heat-treated for applications requiring fastening of soft materials on hard ones. With a lower installation torque, the threads on these screws allow for a quick transition from drilling to tapping. For effective penetration, make sure that at least three threads of the fastener are inside the material.

Applications

Self-drilling screws can be used for a wide variety of applications which involve fastening two different types of materials together. They are commonly used to fasten metal to wood, or even metal to metal.

To name just a few examples, ideal uses could include working with metal roofing, HVAC and ductwork, and steel frames.

▲ Self-Drilling Screws for Wood
While purpose-manufactured wood screws are typically the first choice for tasks involving wood, self-drilling screws may also prove useful in certain woodworking scenarios. For instance, self-drilling screws for wood may be used in the construction, repair, or maintenance of sheds and outbuildings, as well as general construction tasks.

▲Self-Drilling Screws for Plastic
Self-drilling screws can also be used with plastic in certain applications and environments. One instance for using self-drilling screws with plastic could be to fasten sheets or components together when working with ductwork and plastic piping.
