A600504 Ulti-mate II Professional Woodscrew PoziSquare Double Csk Z&Y - (12g) 6mm X 50mm - 200
What this screw is for
These screws are engineered for general woodworking, joinery, and timber assembly where a professional-grade fastener is required. The 50mm length suits fixing timber components, hinges, and fittings where a countersunk head finish is preferred. The slotted shank reduces wood splitting, making them ideal for hardwoods and sensitive applications. The absence of ribs on smaller sizes makes them particularly suitable for use with hinges and other hardware fittings.
- Countersunk head for flush finishing in timber
- Suitable for hardwoods and softwoods
- Ideal for hinges, fittings, and joinery
- Professional-grade construction
Key features and compatibility
The PoziSquare recess is self-centering and accepts both Phillips (PH) and Pozidrive (PZ) drivers, reducing the need for multiple bit types on site. The state-of-the-art anti-camout design ensures stick-fit and stable driving without bit slip. A quick start point allows rapid starting with minimum force, reducing fatigue and improving accuracy. The reinforced double angle head self-countersinks as it drives, eliminating the need for pre-drilling in most applications.
- PoziSquare recess accepts PH and PZ drivers
- Anti-camout design prevents bit slip
- Quick start point for rapid installation
- Self-countersinking head
- Zinc yellow plating for corrosion resistance
Pack contents and sizing
This pack contains 200 screws, each 6mm diameter by 50mm length (12 gauge). The 50mm length is suitable for fixing timbers approximately 30-40mm thick, depending on the application and timber type. Always ensure the screw length allows adequate penetration into the substrate without breaking through the underside.

- Gauge: 12g
- Length: 50mm
- Head type: Double countersunk
Before you install
Check that your driver bit is in good condition and matches the PoziSquare recess precisely to avoid camout. For hardwoods or dense timbers, consider pre-drilling pilot holes to reduce splitting and driving effort. Ensure the timber is dry and free from knots at the fixing point. The slotted shank design already provides splitting resistance, but pilot holes are still recommended for premium results. Store screws in a dry environment to maintain the zinc yellow plating.
- Inspect driver bit for wear or damage
- Pre-drill pilot holes in hardwoods
- Use dry timber free from major knots
- Store in dry conditions
