Lots of info.. bit ott..its a wellbrock on a mast..
Blue locktight, plus nylock locking nut against a plain washer..job done..( on just about anything on land.) only thing that can be an issue is too much of above, (if not using stainless bolts and nuts) that the head is not ¡° get atable¡± ie ¡° bugger¡± the bolt in a plastic housing is spinning, never tighten or loosen them now.. and we do all use stainless for non safety/stess related stuff ie wellbrock to mast outside in all weather conditions don¡¯t we.
Ok not for an aircraft of spacecraft..or submarine etc..
