Woodworking Screw

A wood screw is a rod-shaped metal fastener with external thread, a sharp spear-point tip and a head, for driving into a workpiece made of wood, plywood, chipboard, MDF.

Wood screws speed up furniture assembly and the installation of timber battens and flooring, and allow the product to be carefully disassembled if needed.

Description and installation

Wood screws have the following features:

• material – stainless steel, brass, copper (steel screws are coated with a layer of zinc by electroplating or hot-dip method);
• coating – plain or zinc-plated (obtained by the hot-dip method or by electroplating);
• thread – medium pitch with a sharp profile;
• head types – round (button), countersunk, sometimes hexagon, with plain or cross slots.

No pre-drilling is required for installation: the fastener is driven directly into the material using a screwdriver or power driver.

Selection rules

Depending on their application, wood screws differ in appearance and require different screwdrivers.
