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.
