ForgeFix ForgeFast Pozi Compatible Elite Performance Wood Screw ZY 3.5 x 40mm Box 200 FFP3540Y

ForgeFast wood screws measuring 3.5 x 40mm, supplied in a box of 200, suited to interior use such as battens, framework and thicker joinery where extra penetration depth is needed. The Pozi-compatible drive works with standard tools, and six underhead lobes aid countersinking while reducing surface dust. A reinforced countersunk neck improves holding power.

The anti-friction, serrated thread reduces splitting, jacking and spinning of joined timber, improving pull-out resistance and drawing strength while lowering insertion torque. A double cutting point speeds up drilling, reduces clogging and can pierce 0.8mm steel.

The screws carry an Elementech 400 coating, giving anti-corrosive protection said to last up to six times longer than standard zinc finishes. It contains no Cr6+ and has been salt spray tested to 400 hours.
