Fixing and buying guide

Who this screw is for

This is a professional-grade woodscrew ideal for carpenters, joiners, and experienced DIY users who drive many screws and need consistent performance. The anti-camout recess and stable driving characteristics make it particularly suitable for applications using power tools where bit slip can be problematic. The absence of ribs on this size makes it especially suitable for use with hinges, latches, and other fitted hardware where a clean finish is required.

Sizing and compatibility

At 10g (5mm) diameter and 90mm length, this screw is suitable for general carpentry in softwoods and hardwoods. The PoziSquare recess accepts both PH (Pozidrive) and PZ (square-drive) bits, giving you flexibility in tool choice. The quick start point allows rapid engagement with minimal force, reducing fatigue during high-volume fastening. The self-countersinking double angle head means you can drive directly into prepared timber without countersinking separately in most cases.

• 10g gauge, 5mm diameter, 90mm length
• PoziSquare recess compatible with PH and PZ drivers
• Double countersunk head self-sinks into softwood and hardwood
• Pack of 100 screws

Pre-installation checks

Inspect timber for moisture content and condition before fixing. The slotted shank design reduces splitting, but pre-drilling is still recommended in hardwoods, near timber edges, or in dense softwoods. Ensure your driver bit is in good condition and sits fully in the PoziSquare recess to avoid camout. The zinc yellow plating provides corrosion resistance but is suitable primarily for interior and protected locations; for exposed exterior work, consider stainless steel alternatives. Check that the 90mm length is appropriate for your application, accounting for the thickness of materials being joined.

Key features

The state-of-the-art PoziSquare recess with acro anti-camout technology ensures stick-fit and stable driving, reducing the likelihood of bit slip and screw damage. The reinforced double angle head resists breakage during installation and provides self-countersinking action. The slotted shank reduces wood splitting compared to solid-shank alternatives. The quick start point allows rapid initial engagement, and the absence of ribs on this size makes these screws ideal for use with hinges and fittings where a neat appearance is important.
