Black Phosphate Phillip Drive Bugle Head Corse & Fine Thread Drywall Screw

1. Product Description

Drywall screws name is translated from English Drywall Screw directly over its biggest feature is the appearance of horn head shape,

There are two basic types of drywall screw for installers to choose from. Type “W” units, or wood screws, have wide, coarse threads. They are used for wood framed buildings, where their coarse threading helps them to securely grip the wood. Type “S” screws are designed for use with steel framing members. They have a sharp, notched head that can easily penetrate the steel framing, as well as fine threads that are designed to pass through the steel.

Drywall screws are a type of self-tapping fastener, which means that there is no need to pre-drill holes. These screws almost always have a Phillips head rather than a slotted head, which provides additional control for installers. Instead of a standard drill, installers use a tool known as a drywall dimpler, which has an adjustable nose to install a drywall screw without tearing the paper on each sheet.

A standard drywall screw can be readily identified by its black finish. This black coloring comes from a phosphate mineral coating that is applied to these screws. This coating helps to minimize rusting and corrosion as the screws are exposed to wet joint compound or paint.
