Rated 5 out of 5 by from Fantastic product Had to fix a cabinet to a wall. It was so easy, drill hole size of bolt and screw the bolt in. Never been so easy and could not move the cabinet after. Fantastic product.

Rated 5 out of 5 by from WHAT A BOLT I could not believe my good fortune when these appeared in the Clearance page. Have been using them for a variety of fixing jobs and I have never been let down. As long as you drill the correct dia hole and make it deep enough you cannot go wrong. I have cut some down to a shorter length and they still work without breakout,

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

What size drill bit do you use with the 8mm bolt?

Asked by: JezzaG
Hi Jezza You would need an 8mm drill bit and drill at least 75mm depth and then just screw the bolt in. This is the same across the DEWALT Blue-Tip range, the dimensions of the bolt refer to the dimension you need to drill. 8 x 75mm = 8mm width x minimum 75mm depth.
