A600603 Ulti-mate II Professional Woodscrew PoziSquare Double Csk Z&Y - (12g) 6mm X 60mm - 100
What makes this screw different
The PoziSquare recess is a self-centering design that works with both Phillips (PH) and Pozidriv (PZ) drivers, reducing the risk of bit camout and stripping. The reinforced double angle head is engineered to self-countersink into timber without requiring a pilot countersink, saving preparation time. A slotted shank along the thread reduces wood splitting during installation, particularly valuable in hardwoods and near edges. The quick start point allows rapid engagement with minimum driving force, reducing fatigue on longer jobs.
- PoziSquare and acro anti-camout recess for stable, stick-fit driving
- Self-countersinking double angle head resists screw breakage
- Slotted shank minimises wood splitting
- Works with both PH and PZ screwdriver bits
- Quick start point for fast, low-effort installation
Sizing and suitability
At 6mm diameter and 60mm length, this screw is ideal for general carpentry, hinge installation, and fitting hardware to timber. The 12g gauge provides good holding power without excessive bulk. Smaller sizes carry no ribs on the head, making them particularly suitable for use with hinges and fittings where a flush finish is essential. This pack of 100 suits projects requiring consistent fastening across multiple components.
- 6mm x 60mm length suitable for standard timber joinery and fittings
- No head ribs ideal for hinge and hardware applications
- 100 screws per pack for medium-scale projects
- Zinc yellow plated for corrosion resistance in interior and protected exterior use
Installation and preparation
Pilot holes are recommended in hardwoods and near timber edges to prevent splitting, though the slotted shank design reduces this risk compared to standard screws. The self-countersinking head means you do not need to prepare a separate countersink; simply drive the screw flush with the timber surface. Use a correctly sized PoziSquare or Pozidriv driver bit to ensure full engagement and prevent camout. The quick start point allows you to position the screw one-handed before applying full driving pressure.
- Pilot holes recommended in hardwoods and near edges
- No separate countersinking required; head self-countersinks
- Use matched PoziSquare or Pozidriv driver bit for best results
- Zinc yellow plating provides corrosion resistance for interior and sheltered use
