Optimaxx Extreme Performance PZ Countersunk Wood Screw 4.0 x 50mm Maxxtub 800pc

Summary

The Optimaxx C288-815 is a 4.0 x 50mm flat countersunk Pozi wood screw supplied in a convenient 800-piece Maxxtub. Designed for trade and professional use, it combines a self-drilling, self-countersinking design with hardened steel construction to deliver fast, split-free fixing into timber and sheet materials. No pilot hole or pre-drilling is required, making it ideal for high-volume joinery and general woodworking tasks.

Features

• Self-drilling and self-countersinking - no pilot hole required
• Long thin groove disperses wood fibres on insertion, preventing splitting close to edges
• Saw-tooth formation on lower threads bites into timber, reducing torque and enabling fast penetration
• Double reinforced collar strengthens the underhead area and accepts a wide, deep Pozi recess to minimise cam-out
• Unique 24-groove design self-countersinks into all materials without counter-boring
• Sharp, wide, deep thread with lubricant coating for fast continuous insertion
• Zinc plated and yellow passivated finish for corrosion resistance
• Suitable for hardwood, softwood, PVCu, MDF, chipboard and sheet materials
• Compatible with screwdrivers, combi drills and impact drivers
