ABSTRACT:
A retainer assembly for retaining a bolt in engagement with a first member during assembly or after disassembly of the first member from a second member comprises a retainer formed with a throughbore and an annular slot at one end of the throughbore, a bolt having a shank formed with a smooth section, a threaded section and a groove therebetween, and a triangular-shaped locking ring which is carried within the slot formed in the retainer. The threaded section of the shank of the bolt is first inserted through the locking ring and then into the throughbore of the retainer for mounting within a threaded bore formed in a second member. Upon disassembly of the bolt from the second member, the bolt is moved in the opposite direction along the throughbore of the retainer until the locking ring engages the groove in the shank of the bolt which prevents disengagement of the bolt from the retainer.
