does the ring head clear the bottom bridge of the tester then, and how difficult is it to srew em into the brick
we use these bolt the self tapping yan and then with something similar to the appol tie just the hook goes round the other way in to the centre of the butt used on the fitting. they were tested by some 1 from lloyds t s b bank dont know who he was but he was a jock and every escalaba bo tested poped out so had to be m16 ed in no idea y then poped weather they hadn tapped them selves in properly he type of block sandstone brick or what ever it was under the plaster wasnt strong enought i dont know but first time av ever heard of the excalliber bolt failing ie tests repeatadly any 1 eles have this problem
I knew that SP but they would be no use to us as that thread is useless in granite. We have the single thread bolts where you fix a bracket to take a tube and we also use the hook fitting type where you insert a nylon thread and screw in a smaller hook.
