Spectre Flat Head Timber Fixing Screws – Green

Spectre flat head timber screws are a green-coated structural fixing for joining timber to timber, and in some cases timber to masonry or steel studwork where the spec allows. Two diameters cover most jobs: 6.7mm for general framing and the 8.0mm for heavier sections where you need proper holding power. Lengths start at 65mm and go all the way to 300mm, which should cover anything short of a full-size barn.

The flat head sits flush when driven, so you get a clean finish where cladding, boards or other timber go over the top. The head is driven with a Torx bit, T30 on the 6.7mm screws and T40 on the 8.0mm. If you have ever stripped a Pozi head halfway through a long screw in dense timber, you will know why Torx earns its place in the toolbox. The bit stays seated, the driver stays square, and you waste a lot less time and temper.

Where Spectre Flat Head Timber Screws Get Used

Typical jobs include stud walls, joist to beam connections, ledger boards, decking sub-frames, roof timbers, stair stringers and general carcassing. The longer 8.0mm lengths suit multi-ply beams, sole plates through to substrate where the application allows, and any job where one screw needs to pull two big pieces of timber together and keep them there. The 6.7mm sizes are the everyday choice for 47mm studwork, batten fixing and general site carpentry.

The green finish is a coating that helps the screw resist corrosion in typical site and interior conditions. It also makes the screws easy to spot against pale timber, which is handy for inspections or when you are checking someone else’s fixing pattern. Always check the coating suits the environment. For tanned, treated or exposed timber in wet conditions, confirm the specification before you commit.

Choosing Size and Pack Type

Pack quantities vary by size. Boxes contain 25 or 50 screws depending on length and diameter, while selected 6.7mm sizes are also available in tubs of 200, 250 or 380. Tubs make sense if you are getting through screws on a framing job or a full deck sub-frame. Boxes suit smaller runs or specialist lengths you only need a few of. Check the selector on this page, as not every combination of size and pack type is offered.

As a rough rule, choose a screw long enough to penetrate the receiving timber by at least two thirds of its length for a reliable structural hold, and always allow for the thickness of the piece being fixed through. Get the maths right once and you avoid the screws poking out the back of a board that someone was going to paint tomorrow.

Pair the screws with the correct driver bit from day one. A worn or cheap bit rounds off quickly in dense timber, so a decent T30 or T40 impact-rated bit is worth having in the pouch.
