"Bought these to fix studs to the wall, they work very well!! Just drill the hole in stud, then drill the wall and bang these through, easy as that. Can also screw them in further if not quite tight! Can also uncrew them and take them out, handy if you forget to put the dpc on the stud! Found them to be a bit loose in aerated blocks, but this could be due to me being too heavy handed with the hammer. Drilled a smaller hole and fixed the problem. Have bought more of these!"
"I bought these as a second choice as my local branch had run out of the Fischer fixings i had been using, I found these worked as well as the Fischer fixings that i had been usint to fix timber battens to thermalite blockwork"
