Spectre™ by Forgefix, incorporates a long list of advanced screw features, often only found in premium screws, into what we've named advanced multi-purpose wood screws. They feature a countersunk, pozidrive compatible, recessed head. Fully threaded, up to 50mm, with a sawtooth thread, to prevent splitting, and reamer to prevent jacking (50mm and above). They are also surface hardened with a quick start type 17 slash point. The screws have a zinc yellow passivated finish for excellent resistance to corrosion. Zinc yellow passivation process of electroplating is similar to the 'galvanised' and 'zinc plated' processes, but with the addition of a yellow dye. It offers an aesthetically pleasing finish. CE approved for use in load-bearing timber construction.Select Option 3.0 x 12mm (Box 200)3.0 x 16mm (Box 200)3.0 x 20mm (Box 200)3.0 x 25mm (Box 200)3.0 x 30mm (Box 200)3.5 x 16mm (Box 200)3.5 x 20mm (Box 200)3.5 x 25mm (Box 200)3.5 x 30mm (Box 200)3.5 x 40mm (Box 200)3.5 x 50mm (Box 200)4.0 x 16mm (Box 200)4.0 x 20mm (Box 200)4.0 x 25mm (Box 1000)4.0 x 25mm (Box 200)4.0 x 30mm (Box 1000)4.0 x 30mm (Box 200)4.0 x 30mm, Tub 14004.0 x 35mm (Box 200)4.0 x 40mm (Box 1000)4.0 x 40mm (Box 200)4.0 x 40mm, Tub 12004.0 x 45mm (Box 200)4.0 x 50mm (Box 200)4.0 x 50mm (Box 500)4.0 x 50mm, Tub 9004.0 x 60mm (Box 200)4.0 x 60mm (Box 500)4.0 x 70mm (Box 200)4.0 x 70mm (Box 500)4.5 x 30mm (Box 200)4.5 x 40mm (Box 200)4.5 x 50mm (Box 200)4.5 x 60mm (Box 100)4.5 x 70mm (Box 100)4.5 x 80mm (Box 100)5.0 x 100mm (Box 100)5.0 x 100mm (Box 300)5.0 x 100mm, Tub 3005.0 x 120mm (Box 100)5.0 x 25mm (Box 200)5.0 x 30mm (Box 1000)5.0 x 30mm (Box 200)5.0 x 40mm (Box 200)5.0 x 40mm (Box 500)5.0 x 50mm (Box 200)5.0 x 50mm (Box 500)5.0 x 50mm, Tub 6005.0 x 60mm (Box 100)5.0 x 60mm (Box 500)5.0 x 60mm, Tub 5005.0 x 70mm (Box 100)5.0 x 70mm (Box 300)5.0 x 70mm, Tub 4505.0 x 80mm (Box 100)5.0 x 80mm (Box 300)5.0 x 80mm, Tub 4005.0 x 90mm (Box 100)5.0 x 90mm (Box 300)5.0 x 90mm, Tub 3506.0 x 100mm (Box 100)6.0 x 100mm, Tub 2006.0 x 120mm (Box 100)6.0 x 130mm (Box 100)6.0 x 150mm (Box 100)6.0 x 180mm (Box 100)6.0 x 40mm (Box 200)6.0 x 50mm (Box 100)6.0 x 60mm (Box 100)6.0 x 70mm (Box 100)6.0 x 80mm (Box 100)6.0 x 90mm (Box 100) Add to Basket Quantity
