Optimaxx C288-640 6.0 x 80mm Countersunk Pozi Wood Screws

Summary

The Optimaxx C288-640 is a 6.0 x 80mm countersunk Pozi wood screw designed for extreme performance in timber and sheet materials. Part of the Optimaxx C288 range, these screws combine multiple engineered features to deliver fast, clean insertion without splitting, snapping, or the need for a pilot hole - making them a go-to choice for trade joiners and site carpenters.

Features

• Razor-sharp tip for an immediate, precise start in hard and smooth timbers
• Saw-tooth bottom thread formation bites into timber, reducing torque and enabling fast penetration without pre-drilling
• 24-groove self-countersinking head allows flush seating in all materials without counter-boring or surface damage
• Double reinforced collar strengthens the underside of the head, preventing snapping under load
• Wide, deep Pozi recess significantly reduces cam-out risk during driving
• Long thin fibre-dispensing groove positioned along the shank reduces pressure build-up, preventing splitting close to edges
• Unique lubricant coating on thread formation facilitates fast continuous insertion and provides corrosion resistance
• Part thread design (standard for 60mm and longer) for optimum clamping force
