Optimaxx Extreme Performance Countersunk Wood Screw 6.0 x 180mm Yellow Zinc Box of 50

Summary

The Optimaxx C288-690 is a 6.0 x 180mm flat countersunk, part-thread extreme performance wood screw supplied in boxes of 50. Finished in yellow zinc, it is designed for heavy structural timber joinery and engineered wood applications where speed, reliability, and a clean finish are critical. Its combination of self-countersinking head, lubricant-coated thread, and saw-tooth tip eliminates the need for pre-drilling or counter-boring in most timber substrates.

Features

• Unique 24-slot underside head design self-countersinks into all materials without counter-boring and without surface damage
• Double reinforced collar significantly strengthens the underside of the head, preventing snapping and allowing a deeper Pozi recess
• Wide, deep Pozi recess (PZ3) dramatically reduces cam-out under high torque
• Sharp, wide, deep thread formation coated with a unique lubricant for fast, continuous insertion
• Saw-tooth formation cut into the bottom threads bites into timber, reducing torque and resistance for fast penetration without a pilot hole
• Specifically positioned long thin groove disperses wood fibres on insertion, preventing splitting when screwing close to an edge
• Razor-sharp point at as low as 20deg, with thread extending to the tip for an immediate start in hard or smooth surfaces
• Part-thread shank pulls timber faces together for a tight clamping joint
• Yellow zinc finish for corrosion resistance in internal and sheltered applications
