Ceta Painted Head Decking Screw for Composite Decking, Colour Matched Screw, Coloured Screws, 4.2 x 55mm Stainless Steel Colour Coded Screw, 5 Colours, Pack of 50. (Charcoal (RAL7021) + T15 Bit)

Used these on some composite hollow decking step edge, drilled 2x 4mm pilot holes at slow speed through the decking and a few mm into the wood frame at 40mm and 110mm measured from the top. Then countersink the hole with a number six steadily, then put the screw in, don’t try to over tighten. They worked perfectly, great quality and value. A perfect match for my grey deck.

Used to attach to decking cap as adhesive wouldn’t work Excellent Really good as the grey capping stayed in place even after being hammered into decking

Need care which screwing in as head turn off if one is too heavy handed.

Pretty good colour match to my anthracite decking, no breakages when screwing them in. So good value.

Easy to use. Been down for over a year and still got there coating with no rust or discolouration.

Expensive but do a better job than cheaper alternatives.

Excellent screws value for money and good quality
