ABSTRACT:
The split bolt comprises plural bolt segments having threaded outer surfaces which are brought radially together to render the bolt insertable into a complementary threaded recess, and spaced radially apart to cause the bolt threads to become engaged when an elongated, generally cylindrically shaped wedge member is inserted between the segments to space them into the threaded engagement. The wedge member has plural camming surfaces along the length thereof which engage corresponding camming surfaces on the inside surfaces of the bolt segments. Further, the bolt segments are interconnected by an elastic means which surrounds the segments and keeps them in surface contact with the wedge member inserted therebetween.
