Optimaxx Extreme Performance Pozi Countersunk Wood Screws 5.0 x 40mm - Box of 200

Summary

The Optimaxx C288-520 is a 5.0 x 40mm Pozi countersunk wood screw supplied in a box of 200, finished in zinc and yellow for corrosion resistance. Designed for trade and professional use, these extreme-performance screws combine a self-countersinking head, full thread, and unique anti-split geometry to deliver fast, clean insertion without pilot holes or counter-boring. Suitable for use with screwdrivers, combi drills, and impact drivers across timber, chipboard, and sheet materials.

Features

• Unique 24-groove self-countersinking head - drives flush into all materials without counter-boring or surface damage
• Double reinforced collar strengthens the underside of the head, preventing snapping and allowing a deeper Pozi recess
• Sharp, wide, deep thread formation coated with a unique lubricant for fast, continuous insertion
• Saw-tooth formation cut from the bottom threads bites into timber to reduce torque and resistance - no pilot hole required
• Specifically positioned thin groove disperses wood fibres to prevent splitting when screwing close to edges
• Razor-sharp point starting at the very tip - immediate start even in hard or smooth surfaces
• Zinc and yellow finish provides corrosion protection
