These could really be likened to the traditional coach screw but with the benefits of modern technology. They are plated all over, have a Torx 40 recess for driving and have integral washers so that they do not pull into the timber or other soft materials. Using Spax serrated threads they drive easily into almost any type of material, or into wall plugs, leaving a plated screw fixing that is both neat and tidy in appearance. Sold in packs of 50. A 20% discount is available for 5 or more boxes of the same size. Outside diameter of thread is 8mm.
