ABSTRACT:
A threaded fastener for securing workpieces with a determinable desired clamp load and including a nut assembly and a bolt with the nut assembly including a nut member with a lock base having a load ring portion and a boss portion with the boss portion adapted to be located in a retention counterbore in the nut member and being of a length to provide a gap between the load ring portion and nut and at a predetermined load to collapse and close the gap and be deformed radially into compressive engagement with the threads of the bolt to provide prevailing torque type lock structure resisting loosening of the nut assembly from the bolt with the predetermined collapse load providing the desired clamp load and with the gap closure visibly indicating attainment of the desired clamp load.
