T17 Hex C4 12-11 x 45 Neo

The T17 Hex C4 12-11 x 45 Neo is a Type 17 hex head screw with a sharp cutting point and a bonded neoprene washer under the head. It’s manufactured from hot-dip galvanised steel, giving it a thick protective zinc coating for long-term corrosion resistance in outdoor, structural, and heavy-duty applications. Drives straight into timber without pre-drilling, and the neoprene washer forms a weatherproof seal for outdoor and roofing fixings.
