Woodscrews - Chipboard
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.
