OK, I know that square-headed coach bolts and coach screws have been around for yonks, and that hex headed ones are now widely available. But I've got a job coming up where I've got to insert the best part of 100 square-headed coach screws. Where can I get a socket or nut-driver head which will fit these?
Some of these screw heads will pull below the surface of the wood - even with a washer, once they are tightened, so a spanner is no good. When I ask local suppliers how to overcome this problem, they look at me as if I'm stupid. Am I the only person in the world whose coach-screw heads bite into the surface of the wood?
Help!
