This guide is for DIY enthusiasts and professionals needing reliable fasteners for wood and chipboard projects. The key benefit is the durability and corrosion resistance offered by the zinc-plated steel construction, ensuring a strong hold. A potential caveat is that these screws are specifically sized at 5mm x 20mm, requiring users to confirm this is appropriate for their application. The AB Tools countersunk wood screws feature a single thread and a PZ2 (Pozi head) for secure driving, manufactured from steel for strength and zinc-plated to prevent rust.

These screws are designed for general woodworking and chipboard applications, providing a secure fastening solution with a countersunk head for a flush finish.
You will need a PZ2 (Pozi head) screwdriver or bit for these screws.
The zinc-plated finish provides good resistance to rust and corrosion, making them suitable for some outdoor applications. However, for prolonged exposure to harsh weather, specialized exterior screws may be more appropriate.
This listing is for a pack containing 22 screws.
A countersunk head means the screw head is designed to sit flush with or below the surface of the material it's fastening, providing a neat and smooth finish.
No, these screws are specifically designed for wood and chipboard. They are not intended for use in metal or masonry.
While often used interchangeably for similar applications, chipboard screws sometimes have coarser threads. These specific screws are described as suitable for both wood and chipboard due to their single thread design and material strength.
Ensure you are using a clean and correctly sized PZ2 (Pozi head) screwdriver or bit. Apply firm, consistent pressure and avoid overtightening. If the head is already damaged, try using a screw extractor.
Pre-drill a pilot hole that is slightly smaller than the screw's thread diameter (around 3-4mm for these 5mm screws). This is especially important for hardwoods or when working near the edge of a board.
The pilot hole may be too large, or the material might be too soft. Try using a slightly larger diameter screw or consider using wood filler or dowels to create a more solid anchor point.
Ensure the pilot hole is countersunk to match the screw head's angle. If using a power drill, practice setting the depth or use a countersink bit. The material thickness might also be insufficient for the screw to sit flush.
