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.
