A Coach Screw is a heavy-duty screw with a hexagonal head and an externally threaded cylindrical shaft, tapering to a point at the tip. They're primarily used for heavy timber assembly, attaching metal to timber, and sometimes masonry or concrete. It's essential not to confuse them with coach bolts or carriage bolts.
How to Use a Coach Screw:
Timber: Coach screws require a pilot hole to prevent wood splitting. Use a wood drill bit to drill the pilot hole, with a diameter half the size of the screw for softwood and three-quarters for hardwood. Once drilled, drive the coach screw directly into the wood. For timber, it's advisable to use a washer to prevent the screw head from embedding into the wood and to ease removal.
Masonry: When fixing heavy objects to masonry or brickwork, use an SDS drill bit to drill a hole. To secure the object, use a wall plug with the coach screw, matching the diameter and depth of the drilled hole.
