Products Description
Hex head screw is a kind of screw that is widely used on the surface of building materials, so it is also called roofing screw.
The Hex head self drilling screw with the self drilling point, it can enter the interior of harder and thicker metals. It is
mainly used for fixing color steel tiles (a kind of color steel plate) of steel structures and can also be used for fixing thin
plates of simple buildings.The hex head cap screw is often equipped with a washer. The washer can not only increase the contact
area, reduce the pressure, protect parts and screws, but most importantly, it can upgrade the waterproof ability of the hex washer
head screw. The washer isolates the water, making the screw and the inside of the material less prone to rust due to water
ingress.

Coarse Thread Drywall Screws ：Coarse-thread drywall screws work best for most applications involving drywall and wood studs. But the wide threads are good at gripping into the wood and pulling the drywall against the studs.
oFine Thread Drywall Screws：Fine-thread drywall screws are best for installing drywall to metal studs. But coarse threads have a tendency to chew through the metal, never gaining proper traction. Fine threads work well with metal because they are self-threading.
