Why it works
Fixings matched to the job
No pre-drilling required
Thread-cutting cutter points drive straight into most substrates, so GRP panels and covers fix faster on site.
Corrosion-resistant finish
Bright zinc plate or gold passivate protects the steel body for outdoor and wet-area GRP installations.
Flush countersunk head
The CSK head sits flat in the panel, leaving a smooth surface with no raised fixing points to catch a foot or wheel.
Colour-matched finish
Lacquered black and yellow heads match SSUK's coloured GRP stair treads and nosings for a tidy, professional finish.

Frequently asked questions
Do I need to pre-drill before fitting these screws?
Do I need to pre-drill before fitting these screws?
No. The thread-cutting cutter point is designed to drive straight into most substrates, including timber and thinner steel, without a pilot hole.
Which diameter and length do I need?
Which diameter and length do I need?
It depends on the GRP product and substrate thickness: 4.0mm x 25mm and 4.0mm x 40mm cover most flat sheet and decking fixings, while the 5.0mm x 40mm option suits thicker panels needing a stronger fixing.
Can I match the screw colour to my GRP cover?
Can I match the screw colour to my GRP cover?
Yes. The 4.0mm x 40mm size is available in a lacquered black or lacquered yellow finish to match SSUK's coloured anti-slip stair tread and nosing covers, sold individually rather than by the box.
What's the difference between the gold and zinc plate finishes?
What's the difference between the gold and zinc plate finishes?
Both are steel screws with a corrosion-resistant coating - gold is a gold passivate finish, zinc plate is a bright zinc finish. Either works for general fixing; pick whichever finish you prefer to see against the substrate.
Are these screws sold individually or in boxes?
Are these screws sold individually or in boxes?
The gold and zinc plate finishes come in boxes of 200. The lacquered black and yellow finishes are sold individually so you can buy just the quantity you need for a colour-matched job.
Will these fix GRP panels to concrete?
Will these fix GRP panels to concrete?
Yes, alongside timber and steel substrates. For masonry or concrete, it's worth checking the substrate is sound enough to hold a self-tapping fixing, or using a suitable wall plug first.
What else do I need to complete a GRP installation?
What else do I need to complete a GRP installation?
Most installations only need these screws, but Street Solutions UK's sealant and adhesive for GRP is worth adding where you want a fully bonded, weatherproof edge as well as a mechanical fix.
