The Unifix Self-Tapping Screws with Pozi Flange Head are designed for professional contractors and dedicated DIY enthusiasts seeking efficient, reliable fasteners for wood and metal substrates.

In many wood and thin metal applications, the self-tapping point eliminates the need for pilot holes. However, for dense wood or heavy-gauge metal, a small pilot hole is recommended.
The 6G refers to the gauge or diameter of the screw shank. Always match this to your project requirements.
The screws feature a durable finish designed for corrosion resistance, making them suitable for most standard exterior environments.
While a Phillips driver may fit, it is not recommended as it is likely to cause cam-out and damage the screw head. Always use a proper Pozi bit.
They are manufactured to meet the AB BS 4174 standard.
Ensure the driver bit is the correct Pozi size and is fully seated before applying torque.
Reduce the torque setting on your drill or use a pilot hole for thicker or harder materials.
Switch to a larger head size or incorporate an additional washer to distribute pressure.
To achieve the best results, use a high-quality Pozi-compatible driver bit to ensure a snug fit and prevent rounding of the screw head. Always match the screw gauge (6G) to the pilot hole requirements if the substrate is particularly hard or dense. Store these screws in a dry environment to maintain the finish quality. If using these in outdoor environments, ensure the structure is properly treated to prevent moisture from compromising the area around the screw entry point.
