Jack asked: " had a problem with tight glide bolts on a Samick Grand. The action brackets were in the way making it difficult to turn 
the tight glide bolts. I tried different wrenches but could not get a proper grip to turn the bolts.

What is the fix for this? Lubricate, retap?
Regards,"

Jack,
My usual fix is remove them and coat the threads with Bee's Wax and re-insert. That will usually make them move more smooth, so that you can feel when they are bedded. Other than that, I'd use some heat to make the metal expand and will crush a bit of the wood fiber.
