Hammer fixings work in a similar way to screws and plugs, the hammer fixing screw has a special thread that can be hammered into the plug and loosened / screwed out if required.<br /><br />Installation:<br />Pre-drill a 8mm pilot hole through the item that you're fixing and into the masonry or brickwork. Lightly tap the fixing through the pilot hole with a hammer until the plug is flush. EG. if you're fixing a timber wall plate, the plug fits inside the timber as well as the wall. Once the plug is flush with the timber, hit the head of the screw harder to drive it into the plastic sleeve until tight.<br /><br />Minimum fixing depth: 45mm">
