anchor bolts

[diditrain]

Hi all, does anyone have a foolproof method for fixing anchor bolts.
I am trying to fix some angle brackets using anchor bolts and have drilled my holes to the size specified but on some occasions the bolts fail to tighten up so i have to re-drill and try again. Wasting time and bolts.
Many thanks for replies

Yep. Find this on many an occasion.

It can be a bit hit and miss to be honest, so i have started using the resin kits.

More expensive but a lot less hassle.

i take it you use a tool to bang the anchors in first, to open them up, can't remember what its called, funny name,

bored and just in from a back shift. Hawk the name we call it in Scotland is a "Poger" but i belive the proper name is a Pin punch.
