Chipboard is made up of wood dust or wood chips, and resin. As such, it has no natural grain to resist a screw withdrawing. Chipboard screws have a thin shaft and coarse threads. This avoids splitting and the coarse grain keeps them securely in place. They can be used to fasten chipboard to chipboard, or chipboard to wood. They are most often used in cabinetry and flooring. We stock a large range of sizes in countersunk and pan head styles, in both A2 and A4 Stainless Steel.
