Rated 4 out of 5 by from bolts to the wall? no plugs? had read other reviews about these bolts and decided to give them a try, i've always liked to pop in a plug ;o) but these, just drill your hole with a 10mm sds bit, and screw in, nice and tight... did 5 in about 5 mins, excellent fixing so far... time will tell if they last... or the wall falls down.

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.

What size drill bit would be used for the 8mm concrete screwbolt

Asked by: Argall
This would require an 8mm drill bit
Answered by: DEWALT Product Expert
Date published: 2017-03-21

Suitable for wood?

Would these go through plasterboard then into wood support frame then finally into breeze block (if they reach). I'm wanting to hang a 24kg pull up bar which will additionally need to hold my 100 kg of blubber! If not any advice? Thanks Steve

Whats Pre Drill Size should I use for a 6mm Screwbolt

Asked by: dj1967
The size of the bolt is the size of the drill bit you would require. 6mm bolt will need 6mm drill bit. 100mm long is obviously the length you need to drill.

I want to use these to fasten a bolt down fence post support to concrete. I haven't laid the concrete yet. What is the minimum depth of concrete necessary to use the 75mm concrete fixing?

Asked by: Suzeee
You can get away with 75mm deep concrete as long as you're not drilling too close to the edge. Ideally you want to be at least 50mm from the edge.
