Thank you Ian. That is the issue I've been thinking about. Makes good sense to countersink the back and use a tapered screw. Wondering if I should do all six at once so I don't have a repeat of this problem.
Regards,
James
I'd leave any sound screws in place...It's very rare that they fail in use, rather at the time they are done up..Fit a spring washer under each nut and resist the temptation to swing on the end of the spanner..A medium grade Loctite 'threadlock' would help in that regard as well...Ian
