Double Countersunk Head Construction Wood Screws Coarse Thread / Fine Thread Type

Carbon steel 1022 Pozi double countersunk head chipboard screw & drywall screw

Product Description

Chipboard Screws, as the name suggests, these screws can be used when doing general DIY work with chipboard and other softer types of woods.Unlike the Cut screws, they do not have the Type 17 cutting point and, therefore, require pilot holes, drilled 2mm smaller than the size of screw used. A Pozi screwdriver bit is then required to drive the screws home, but care must be taken as they have a tendency to slip and strip.

Drywall Screws, 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).

Product Specification
