4.0 x 50 (800) Optimaxx Performance Woodscrew Tub

Optimaxx is a top quality high performance wood screw that incorporates a number of unique features.

A specifically positioned long thin groove dramatically reduces the pressure build up on insertion by dispensing wood fibres, preventing splitting when screwing close to the edge. Finally a sharp saw-tooth formation cut out of the bottom threads bite into the timber reducing torque and resistance, enabling fast penetration without a pilot hole.

Features:

• Unique 24 slots self countersinks into all materials without any surface damage whatsoever.
• Double reinforced collar strengthens underside of the head and allows for a wide deep pozi to be punched.
• Sharp, wide, deep thread formation coated with a unique lubricant.
• Sharp saw-tooth formation cut out of the bottom threads enable fast penetration without a pilot hole.
• Razor sharp point with thread beginning on tip, gives an immediate start even in the hardest, smoothest surfaces.
