The ForgeFix Spectre™ Screws are advanced multipurpose wood screws with double countersunk heads and pozi compatible recess. They have a sawtooth thread design to prevent splitting and reamer to prevent jacking. The screws have a zinc yellow passivated finish for excellent resistance to corrosion. The 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.
