Many in engineering circles view lock nuts, lock washers, threadlocker, and the like as a band- aid for a fundamentally poor bolted joint design. One of the most important things is to have sufficient length of bolt available to stretch when torqued. A long bolt stretched to just below the yield point will stay tight long after an equally-torqued short bolt comes loose. For this reason a bolted joint of two thinner pieces of material that is subjected to vibration or impacts can present a challenge. Many loose hardware problems can be solved by simply adding a quarter or half inch of bolt length and an equal length spacer under the head or the nut. Use hardened flat washers at each end of the joint so that the hardware doesn't sink into the base material. If properly torqued with sufficient bolt stretch the actual shape of the hole (within reason) doesn't matter much since there should never be relative movement between the two pieces - if there is the joint has failed. Anything short of a press fit of the bolt in the hole will have some slop anyway and if the parts are moving relative to each other a little slop will turn into lots.
