Coloured wafer head self drilling screws from RALfixings - powder coated tek screws in 40+ RAL colours for fast metal-to-metal fixing where no pre-drilling is required.

The self-drilling tip acts as both drill and thread-cutter in one pass, penetrating steel substrates up to 3mm without a pilot hole. Combined with the low-profile wafer head - wide diameter, minimal height, flat bearing face - these are the standard fixing on site for ACM hoarding panels, signage installation, sheet metal stitching, and cladding system work where speed of installation matters as much as a clean, colour-matched result.

Available in BZP steel in 13mm, 16mm, 19mm, 22mm, and 25mm, powder coated in-house to any of our 40+ stocked RAL colours with the full RAL Classic range available to order. Where a pre-drilled hole is already prepared or penetration depth needs to be controlled, see our Coloured Wafer Head Self Tapping Screws. Standard lead time 3–5 working days.
