Customized Coarse Thread Drywall Screws / Multi Purpose Wood Screws Fasteners

Carbon Steel White Zinc Plated Coarse Thread Drywall Screw

Product Description

As the name implies, a drywall screw is used to fasten drywall — wallboard made of a heavy paper-coated layer of gypsum — to framing. The drywall screw is constructed with either coarse or fine threads. The choice of which to use is determined by the type of framing, whether wood (coarse) or metal (fine).

Drywall screw coarse thread

The drywall screws with coarse thread can be used to secure drywall to a wood substrate, such as studs or roof brandering, as strong holding power is required.

Coatings

The drywall screw, threaded its whole length to aid in installation, will have its steel length coated in zinc or phosphate. The phosphate coating, which is black in appearance, is preferred, as it is the more rust-resistant. However, this does not sanction use in wet or exterior situations. Zinc-coated screws, when they begin to rust, will damage any plaster and wall finish applied over them.
