Rated 5 out of 5 by Great masonry fixing Used these concrete screw bolts to fix a fence post to a brick wall, and to bolt down a post support box on a concrete slab. They installed a lot easier than expected, cutting thread in brick and concrete easily in the 10 mm pilot holes. The small edge distance tolerance was really helpful for the fixings to the concrete slab. Will use again. 12 Sep 2016
Rated 4 out of 5 by Good strong fixings Was worried about these from other review comments, but found they were easy to use and held a wooden beam to a brick wall very well. Much stronger and more secure than rawlbolts, and the bolt head looks better than the more expensive expanding fastners. 31 Aug 2016

Rated 5 out of 5 by Best concrete bolts I have purchased similar bolts from other retailers, but these were excellent value for the money in comparison. There were also very strong and easy to use and reliable. I will defiantly be recommending these to friends. 30 Mar 2016
