Product Overview
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.
Countersunk / Double Countersunk Head
The flat-head makes the chipboard screw stay level with the material. In particular, the double countersunk head is designed for increased head strength.
Thin Shaft
The thin shaft helps to prevent the material from splitting.
Coarse Thread
Compared with other kinds of screws, the thread of the screw MDF is coarser and sharper, which digs deeper and more tightly into the soft material such as particleboard, MDF board, etc. In other words, this helps more part of the material to be embedded in the thread, creating an extremely firm grip.
Self-tapping Point
The self-tapping point makes the screw of particle board more easily driven into the surface without a pilot drill hole.
Nibs (Optional Feature)
Besides, the chipboard screw may also have other features, which are not necessary but might improve the fastening processes in some applications: The nibs under the head help to cut away any debris for easy insertion and makes the screw countersink flush with the timber.

Frequently Asked Questions (FAQ)
1. What is a chipboard screw used for?
Chipboard screws, also known as MDF screws or particleboard screws, are specifically designed for fastening low, medium, and high-density wood materials such as particleboard, MDF, and softwoods.
2. Why do chipboard screws have a double countersunk head?
The double countersunk head design increases head strength and helps the screw sit perfectly flush with the wood surface, reducing the risk of head shear during installation.
3. Do I need to drill a pilot hole before using chipboard screws?
Generally, no. Thanks to the self-tapping point and sharp threads, chipboard screws can be driven directly into softwoods and particleboard without pre-drilling.
4. What are the nibs under the head of the screw for?
The nibs act as tiny cutters that clear away wood debris during driving, allowing the screw head to countersink cleanly and sit flush with the timber surface.
5. How does the coarse thread benefit wood applications?
The coarse and sharp thread digs deeper and holds more tightly into soft wood fibers and composite boards, creating an exceptionally strong grip that resists pull-out.
