KKT COLOR is a cone-shaped concealed-head decking screw in A4 / AISI316 stainless steel with an organic-coated coloured head in brown, grey or black. The small conical head sits flush in the timber and the coating camouflages the fixing against the deck or facade board for a clean finish. Built for outdoor use in highly aggressive environments such as coastal, chemically treated or carbonised timber.
