Abstract
A nutless bolt includes a body having a shaft and a stop coupled to the shaft. Shaft is dimensioned to allow passage through a hole formed in a structure into which the bolt is inserted. The stop prevents body from falling into or through the hole. An axial bore formed in body houses a locking mechanism extending radially from shaft to lock body and nutless bolt in the hole. An actuator pin movable along the bore in a generally down hole direction through various positions. Position L1 is a pre-application position; position L2 is a locking position; and position L3 is a release position. Pin is movable in the down hole direction from L2 where the pin causes the locking mechanism to extend radially from shaft to lock the body in the hole, to L3 where the pin is retained in the body and displaced relative to the locking mechanism.
