Advantages

Benefits of Hex Cap Screws

With their hexagonal shape, hex cap screws allow for greater torque than that traditional screws with a circular head. You can't install or remove them using a standard screwdriver bit like a flat head or Philip's head. Instead, you'll have to use a ratchet and socket combination.

Benefits of Self Drilling Screws

A Self-drilling screw is, essentially a self-tapping screw with the added feature of a drill point end. Self-drilling screws eliminate the need for a pre-drilled pilot hole as they perform the drilling, tapping, and fastening in one action. Hardened steel fixings are generally used when fixing metal to metal or metal to timber.

Application

Self-Drilling Screws for Metal

Self-drilling screws can be used to fasten sheets of metal to another material, or even to join metal to metal. Not only does this set them apart in comparison to other common screw types, but it also makes them highly useful across a broad spectrum of industries and applications. 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 of using self-drilling screws with plastic could be to fasten sheets or components together when working with ductwork and plastic piping.
