Woodscrews - Chipboard - Pozidrive Countersunk - A2 Stainless Steel

Chipboard woodscrews are best when used with softwoods, chipboard, plastics and some hardwoods. Many builders and carpenters use chipboard screws as their “go-to” screw for general timber use.

Chipboard screws have been purposely designed for fastening into wood. They generally have a thinner shaft and a single coarse thread, which cuts into soft materials quickly. The thread of a chipboard screw is self-tapping and it runs all the way along the shaft to the underside of the screw head.

Chipboard screws have an exceptionally high resistance to pull-out forces.

When it comes to the sizing of chipboard screws it is still very common to find measurements in both metric and imperial. The diameter of a wood screw is either given in a gauge (imperial), or in millimeters (metric). With the imperial gauge, a number is used, i.e. 8 gauge. A larger gauge number means a larger diameter. Screw gauge numbers actually correspond to a particular fraction of an inch in imperial measurements.

Screw lengths are also often shown in either metric or imperial sizes, or sometimes both.

A countersunk head is usually used when no part of the fastener head is required to be protruding above the level of the substrate. Countersunk heads can also be recessed and filled over if a hidden fixing is required. Usually abbreviated to CSK.

A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy - 18% chromium and 8% nickel.

A2 stainless is the most common type of steel used for the manufacture of fasteners and is suitable for general use.
