The ForgeFix Spectre Advanced Deck Screw is a 4.5 x 50mm countersunk, Pozi drive outdoor screw with a green coated finish, supplied in a tub of 1000. Designed for softwood and hardwood decking, fencing, pergolas, raised beds and all exterior timber construction where corrosion resistance and clean driving are essential.
The green coating provides long-term protection against moisture, treated timber chemicals and general weathering, making these screws suitable for use with tanalised and pressure-treated softwood without risk of chemical reaction or premature corrosion. The colour blends with treated timber for a discreet finish on visible deck boards.
Spectre deck screws feature a sawtooth thread profile that cuts cleanly into both softwood and hardwood, reducing the splitting risk that standard wood screws cause near board edges and ends. A reamer section below the head prevents jacking, pulling the top board tight to the joist without the head lifting off the surface. The Type 17 slash point provides a fast, clean start without pre-drilling in softwood, though pilot holes are recommended in hardwood and near board ends.
The Pozi drive recess is compatible with standard PZ2 bits and provides reliable torque transfer for powered driving. Surface hardening extends the working life of the screw tip and thread in abrasive timbers.
