摘要：
An hydraulically assisted fastener has a pressure means (13) nested in a recess (15) or groove in a nut (11) or a thrust washer with a filler neck (20, 31, 44) whereat a nipple (14) can be used as a means of pumping grease or oil to the pressure means. The pressure means can be a bladder (13) or two parts with mated channels (42, 43). Alternately the pressure means (13) can be a single part with open channel (45) nested in a channel (46) in a nut body or thrust washer.
