These ForgeFix ForgeFast Wood Screws have a universally accepted, Pozi compatible drive. They have 6 underhead lobes for improved countersinking and reduced surface dust, and reinforced countersunk necks which improve holding power. The screws have an anti-friction thread for reduced splitting of the timber, reduced 'jacking' and spinning of joined timber and improved drawing strength. The thread is serrated for improved pull-out and reduced torque when inserting the screw. The double cutting point allows faster drilling time and reduced clogging of wood dust and is capable of piercing 0.8mm steel. The screws have an 'Elementech 400' coating providing an anti-corrosive metal finish, which lasts up to 6 times longer than standard zinc coatings. The coating is environmentally friendly and does not contain Cr6+. It is salt spray tested to 400 hours. The screws are suitable for interior and exterior use.Select Option 4.0 x 20mm Tub 18004.0 x 25mm Tub 16004.0 x 30mm Tub 14004.0 x 40mm Tub 12004.0 x 50mm Tub 9004.0 x 60mm Tub 7004.0 x 70mm Tub 6005.0 x 100mm Tub 3005.0 x 40mm Tub 8005.0 x 50mm Tub 6005.0 x 60mm Tub 5005.0 x 70mm Tub 4505.0 x 80mm Tub 4005.0 x 90mm Tub 350ZY 3.5 x 30mm Tub 1600 Add to Basket Quantity
