The Unifix Twinthread Woodscrews are essential fasteners for woodworkers, DIY enthusiasts, and trade professionals looking for reliable, high-grip performance in various timber projects. Featuring a durable, bright zinc-plated (BZP) finish, these screws provide excellent corrosion resistance for long-term hold, though they are specifically optimized for indoor or dry-environment wood applications rather than heavy-duty exterior load-bearing structures.

This specific item contains 200 screws.
Ensure you are using the correct Pozi-drive bit size and apply more forward pressure while driving.
Drill a pilot hole slightly smaller than the shank diameter before driving the screw.
Check if the pilot hole is sufficient or apply a small amount of candle wax to the screw threads to reduce friction.
To ensure the best results, use a manual screwdriver or a power drill with a torque-limiting clutch set to low. Using excessive force can damage the screw head or strip the thread in softer wood.
