Hardware question

I am working on a build and am using some 180 adjustable connectors as well as a few other pivoting connectors. I will be using these for a table that will be moved and folded/ unfolded frequently. Has anyone used these pieces for a heavily utilized and often transported project. My concern is that the hardware will loosen, and I will lose nuts and bolts. I am considering locking washers. Either that or using smaller diameter hardware (possibly even rivets) with nylon bushings. Any advice?
