Product Description

Drywall Screw

Drywall screws are used when working with drywall, as the name suggests. They are a popular type of fastener that allows users to secure sheets of drywall/plasterboard to walls and ceiling joists. Drywall screws are designed to secure drywall to both timber and metal studs and frames.

Drywall screws have deeper threads than regular screws, which prevents them from dislodging easily from the drywall. They are made of steel and require a power screwdriver to drill them into the drywall.

Self-tapping Screw

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in relatively soft material or sheet materials, excluding wood screws. Other specific types of self-tapping screw include self-drilling screws and thread rolling screws.

Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened.
