The Chipboard Screw is also called Screw for Particleboard or Screw MDF. It’s designed with a countersunk head (usually a double countersunk head), a slim shank with an extremely coarse thread, and a self-tapping point.
Furniture Chipboard / Twinfast Screws, also known as particleboard screws. These self-tapping screws have a coarse thread with twice the thread pitch of standard wood screws, making it easy to drive them into a variety of materials such as chipboard or various densities of fibreboard.
The advantages of these screws are numerous. Despite having very high tensile strength, these screws are easy to use and prevent the surface from cracking or splitting even without the use of a washer.
The main difference between woodscrews and chipboard screws lies in the threads which, on a chipboard screw, run all the way along the screw’s length to the underside of the head. This makes chipboard screws particularly useful where an extra-strong hold is required, such as when installing garden decking.
The chipboard screw is mainly used for woodworking. For this reason, the thread is deeper and bigger than the countersunk head screws for a larger gripping force in the wood material.
For very soft timbers, MDF or chipboard, you need to use chipboard screws.
