The Unifix General Purpose Chippy Woodscrews are an essential fastener for DIY enthusiasts and woodworkers looking for a reliable, easy-to-drive solution for general assembly tasks. These silver, bright zinc-plated screws feature a Pozi countersunk head designed for a secure, flush finish in timber projects. While they offer excellent grip and durability for standard wood applications, users should ensure the screw gauge and length are appropriate for their specific material thickness to avoid splitting.

These screws have a bright zinc-plated finish, which offers some protection, but they are primarily designed for indoor or protected applications.
These screws feature a Pozi-drive recess and require a corresponding Pozi-drive screwdriver bit.
While often unnecessary in softwoods, pre-drilling a pilot hole is recommended when working with hardwoods or near the edge of a board to prevent splitting.
Yes, they are suitable for most general woodworking materials, including MDF and chipboard.
The 5.0mm refers to the diameter of the screw shank, and the 35mm refers to the total length of the screw from the top of the head to the tip.
Ensure you are using the correct size Pozi-drive bit and apply consistent, steady downward pressure while driving.
Always pre-drill a pilot hole slightly smaller than the shank diameter of the screw when working near the end grain or edge of a board.
Check that the countersunk hole is properly cleared or that the screw is driven perpendicular to the surface.
To achieve the best results, select the appropriate screw length for your project—ideally, the screw should penetrate the secondary material by at least two-thirds of its length. These screws are compatible with standard manual screwdrivers and power drill-drivers. To care for these fasteners, store them in a cool, dry environment to maintain the integrity of the zinc plating. Avoid using these in direct contact with chemically treated woods that may cause rapid corrosion, and always ensure the screw head is tightened until flush to prevent catching or damage to the workpiece surface.
