Fixing and buying guide

What this product is and who it is for

These are professional-grade woodscrews engineered for demanding applications where driving reliability and finish quality matter. They suit carpenters, joiners, and experienced DIY users installing hinges, fittings, and structural timber connections. The PoziSquare recess works with both PH (Phillips) and PZ (Pozidriv) drivers, offering flexibility on site. The slotted shank reduces wood splitting, making them ideal for hardwoods and close-grain timbers where traditional screws may cause damage.

Key features and compatibility

The double countersunk head self-sinks into timber without requiring a pilot countersink, saving preparation time on site. The quick-start point penetrates timber rapidly with minimal driving force, reducing operator fatigue and bit slippage. Absence of ribs on the shank makes these screws particularly suitable for use with hinges and metal fittings where a clean, flush finish is essential. Zinc yellow plating provides corrosion resistance for both internal and external applications.

• PoziSquare recess: anti-camout design prevents bit slip and ensures stable, stick-fit driving
• Reinforced double angle head: self-countersunking and resistant to breakage under load
• Slotted shank: reduces splitting in hardwoods and close-grained timbers
• Compatible with PH and PZ drivers for on-site flexibility
• Zinc yellow plated for corrosion protection

Sizing and pack contents

Each screw measures 5mm diameter by 70mm length, making them suitable for joining timber sections 40-50mm thick with adequate penetration into the receiving member. The 200-screw box is a standard trade pack, sufficient for approximately 20-30 linear metres of hinge installation or comparable joinery work. Confirm your timber thickness and application before ordering to ensure adequate screw length for your project.

Pre-installation checks

Inspect timber for moisture content and grain direction before fixing; the slotted shank performs best in properly seasoned wood. For hardwoods or dense timbers, consider drilling pilot holes to prevent splitting, particularly near timber edges. Ensure your driver bit is in good condition and fully seated in the PoziSquare recess to maximise the anti-camout benefit. Store screws in a dry environment to maintain the zinc yellow plating integrity.
