Hi folks , im just in the middle of a job using Greenheart , which has 16mm bolts coming through it to hold it in place. Bearing in mind it then gets a washer + nut on & i will need a socket to tighten the nuts as they will be in a recess , which will then get plugged. My questions are ( i havent worked out a size for the socket yet ) can you get plug cutters with a big enough diameter for this , could you use something else , eg a holesaw . Really what would give the best finish , forgot to say the plugs will only need to be 35mm long or thereabouts. ps if its the plug cutter route , does anyone know a supplier, this is quite urgent so any advice would be much appreciated , thanks < Tony
