Heavy-duty M8 hex head coach screws deliver secure timber and masonry joints. Made from high-tensile carbon steel with bright zinc plating (BZP) for outdoor use. The hex head accepts a 13mm spanner or socket for high torque and minimal cam-out. Deep coarse thread provides strong pull-out resistance for decking frames, fencing, posts, and timber framing. For masonry, use with a nylon wall plug. Pre-drill a pilot hole (4-6mm: 4mm softwood, 6mm hardwood). Drive fully and consider a washer under the head to distribute load in softer woods.
