Fixing and buying guide

What this product is and who it is for

These are professional-grade woodscrews designed for cabinet making, joinery, furniture assembly, and general carpentry where a neat countersunk finish is required. The 4mm x 70mm size suits medium timber thicknesses and is particularly effective for hinge installation and fitting work. Suitable for both trade professionals and experienced DIY users who demand reliable performance and quality finishes.

Key features and compatibility

• PoziSquare recess with anti-camout technology for stick-fit and stable driving without bit slip
• Accepts both PH (Phillips) and PZ (Pozidriv) drivers for on-site flexibility
• Reinforced double angle head self-countersunks into timber without pre-drilling in most applications
• Slotted shank design reduces wood splitting and splitting risk in dense timbers
• Quick start point allows rapid engagement with minimum driving force
• No ribs on the shank making them ideal for use with hinges and metal fittings without obstruction
• Zinc yellow plating provides corrosion resistance for interior and exterior use

Sizing and pack contents

Each box contains 200 screws at 4mm diameter and 70mm length (8 gauge). This size is suitable for joining timber sections of 40-50mm thickness and is commonly used in cabinet work, door frame assembly, and furniture construction. The countersunk head sits flush with the timber surface when fully driven, ideal for applications where a neat finish is essential.

Pre-installation checks and best practice

• Check timber moisture content is between 12-18% for optimal screw performance
• For hardwoods or dense timbers, consider pre-drilling pilot holes to prevent splitting
• Use a correctly sized PZ or PH driver bit to avoid recess damage and bit slip
• Ensure the driving tool is held square to the screw head for consistent countersinking
• Test on scrap timber first if working with unfamiliar timber species
• Store in a dry environment to maintain zinc plating integrity
