Easydrive Countersunk Concrete Screws 7.5 x 100mm 100 Pack is rated 4.7 out of 5 by 12.
Rated 3 out of 5 by from Not for Thermalite blocks? It's obvious from the reviews that these are a good product BUT I found them less than useless when trying to fix kitchen wall-unit hanger plates through Dot&Dab'd plasterboard and into Thermalite blocks. (just sharing the experience folks)

Rated 5 out of 5 by from Brilliant! I used these to batten out a shower enclosure, the walls of which were really out of true - not straight, not plumb, built out of multiple different types of brick and block... would have been a right pain with normal plugs and screws! I just used expanding foam and a few spacers to get the timbers in position and when it had gone off drilled and fixed with these screws. 18v cordless impact driver got them into solid brick and cinder blocks with no sweat, just make sure you use a decent 6mm masonry bit to pilot first. Then No More Ply cement backer boards on the battens ready for tiling. Rock solid and a piece of cake. Very happy!

Rated 3 out of 5 by from Immensely strong Alas, this did not perform as advertised. Maybe it was because I was working with soft bricks? Instead of penetrating the substrate, it simply churned the brick dust out leaving the screw to waggle about. I tried drilling a 6mm tap hole as some reviewers have recommended but it only made matters worse. In the end, I drilled a clearance hole with an 8mm masonry drill and inserted a big plastic Rawlplug. My 18v Bosch was defeated half way but I successfully drove it home using a socket spanner and T30 bit. I bought this product because of its advertised labour saving claims but it failed on this criterion in spite of being an incredibly strong screw.

Rated 5 out of 5 by from Superb These save so much time compared to the traditional plug method. Used the 100mm to fix 3x2 studs to concrete blocks. Just remember to 'clear out' the last inch of dust and debris when drilling, otherwise they'll sometimes stop the screws from going all the way in.
