The FIX-HP4-8 is an 8 mm multi-tooth design screw anchor and plug system used to provide secure fixings in concrete, natural stone and masonry materials. The FIX-HP4-8 consists of a threaded metal screw anchor and a plastic plug which, when screwed together in the hole, create a strong fixing. The screw anchor has a unique "multi-tooth" design which grips securely both in medium to hard materials and provides a high pull-out resistance. The anchor is also simple to install, requiring only a hammer drill and the FIX-HP4-8 setting tool. This versatile anchor system is designed for a wide range of applications, including anchoring handrails, valves, pipes, conduits and other materials into concrete, natural stone and masonry materials.
