ForgeFix ForgeFast Wood Screws feature a universally accepted, Torx(r) compatible drive. Their recessed ribs offer improved countersinking and reduced surface dust, while reinforced countersunk necks enhance holding power. These screws boast a patented drill and drive thread designed to minimize timber splitting, reduce 'jacking' and spinning of joined timber, increase pull-out strength, and ensure a firmer fix. A sharp point allows for faster bite and can pierce 0.8mm steel. The 'Elementech 400' coating provides an anti-corrosive metal finish that is up to 6 times more durable than standard zinc coatings. This environmentally friendly coating does not contain Cr6 and has been Salt Spray tested to 400 hours, making the screws suitable for interior use. Each box includes a Torx(r) compatible bit. Size: 4.0 x 35mm. Box quantity: 200. These are elite performance multi-purpose woodscrews with an Elementech 400 surface coating for corrosion resistance. The deep Torx compatible head reduces cam-out, allows for higher torque levels, and ensures a firmer drive. The patented drill/drive shank provides faster drive, reduces timber splitting and 'jacking', increases pull-out, and ensures a firmer fix. They flex up to 35° to reduce the likelihood of screw shearing when used in substrates that flex in use.
