1. What is Chipboard Screw?

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.

The 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.

The thin shaft: The thin shaft helps to prevent the material from splitting

The 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.

The self-tapping point: The self-tapping point makes the screw of particle boar more easily driven into the surface without a pilot drill hole.

Besides, the chipboard screw may also have other features, which are not necessary but might improve the fastening processes in some applications:

The nibs: The nibs under the head help to cut away any debris for easy insertion and makes the screw countersink flush with the timber.

2. What is the difference between chipboard, particleboard, and MDF?

As we mentioned before, the chipboard screw can also be referred to as screw for particleboard, screw MDF, etc. However, there’s difference between these different materials:

Chipboard:

The chipboard is also known as particleboard, is a composite wood product that is pressed and extruded from wood chips and a synthetic resin or another appropriate binder. This kind of material has a wide usage such as chipboard flooring, chipboard loft panels, or furniture production, etc. And the melamine-faced chipboard is popular for decoration.

MDF:

MDF is the abbreviation of Medium Density Fiberboard. 90% of MDF plates consist of wood. MDF, which is not readily available in nature, is a man-made wood material. It is obtained by compressing wood fibers through heat treatment.

Generally, the MDF is harder than the chipboard.

3. What’s the difference between the chipboard screw and the countersunk self-tapping screw?

Tough the countersunk self-tapping screw is also featured with a flat head and a sharp point. There’s still a difference between chipboard screw and countersunk screw:

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.

On the other hand, the deeper the thread is, the bigger the deformation it makes on the material. For this reason, the chipboard screw is suitable for particle board or MDF board while the countersunk head screw makes smaller deformation driving into the sheet metal.

4. Where to use the chipboard screw and how to use it?

The chipboard screws are mainly used for woodworking such as furniture assembly or flooring, etc. This is why we also call it screws for particle board or screws MDF. We offer a wide range of chipboard screws whose length is from 12mm to 200mm. Generally, the small chipboard screws are perfect for fastening hinges on chipboard cabinets while larger screws are used to join the bigger pieces of a cabinet, etc.

Basically, there are two kinds of chipboard screws: white zinc plated or yellow zinc plated. The zinc plating isn’t only a layer of protection to resist corrosion, but also matches the aesthetic of the project. Besides our chipboard screw is characterized by a deeper Pozi recess that helps to avoid cam-out and also extends the life of the bit used to drive the screw.

Main tips of the applications are the followings:

The screw MDF should be driven with more than an inch from the edge of the material.

The chipboard screw should be driven into the material with more than 2.5 inches from the end.

The over-tightening should be avoided for it might weaken the hold of the board.
