Broken hex bit stuck

[Old Bob]

Yeah, what NugginFutz said. When used correctly, torque wrenches can prevent a lot of problems when putting anything together that uses screws or other threaded devices in their assembly. The F.A.T. wrench is good - used one for ages - but the Fix it Sticks torque devices work pretty well also. Google "small screw torque tables" & look at some of the torque specifications tables if you're unsure what torque to apply to a screw. It'll save you some consternation...
