Ok... I have an application where I need to pull to items together, and use a locking nut/bolt combination. Because of the location it needs to be stainless. So far my attempts have met with limited or no success. The stainless nut and bolt tend to gall and sieze before pulling the two pieces fully together. Just for the heck of it I tried it with plane old grade 5 steel bolts & nuts and it cinched it down just fine.
What can I do to get a locking application using stainless bolts that will draw down without galling before its tight?
One thing I thought of was to use nylocks with never sieze compound. I just wonder if the never sieze will keep the nylocks from getting warm enough to melt the plastic and/or if it will keep it from locking in place once its tightened down?
The only other idea I had was to use a plane stainless nut with never sieze, clean the bolt thoroughly and then run a second nut on with red loctite to double nut it in place. It is not possible to use an external clamp to compress the pieces together that are being bolted.
