DeWalt Blue-Tip Concrete Screwbolt Hex Head 8 x 100mm 25 Pack is rated 2.3 out of 5 by 3.
Rated 5 out of 5 by from Better the rawl bolts Great product with an excellent hold and really easy to use

Rated 1 out of 5 by from Poor performance We ordered these as an alternative since Screwfix have stopped supplying the Multi-Fix product, the pitch on the thread is 6mm rather than the 10mm on the Mutli-Fix bolts which means that they bind up very easily and refuse to budge in or out, thus causing snapped heads or bolts not home fully that have to be removed by other means, we've tried reaming the hole out a little more but that isn't the solution as they should go straight into an 8mm hole. In summary a very poor product.

Rated 1 out of 5 by from Retract M8x75 review I've just set 60 of these into both old and green concrete and they're awful. So much re-drilling because as soon as they hit something hard, they bind up, presumably because the thread blunts instead of cutting through. As it happens (can you still say that?), I found some Heco Multi Montis on my shelf (that screwfix used to sell) and whizzed the last post holder in, first time. Anything that fights you getting the job done is a drag 'cause it's hard enough work to start with. Gotta find summat better.
