ABSTRACT:
A safety bolt having a headed end, a shank, and a second end with means near the second end to hold the bolt in a hole in a workpiece. An axial passage opening into the second end intersects a laterally-extending passage spaced therefrom, and a dog fits in the laterally-extending passage wherein it is laterally reciprocable so as to be extendible beyond the maximum diameter of the shank or to be entirely retracted within it. A cam member having a pair of oppositely facing cam surfaces is axially slidable in the axial passage. The dog has a pair of followers one on each side bearing against oppositely directed cam surfaces whereby the lateral position of the cam is uniquely a function of the axial position of the cam member. Bias means is provided to bias the cam member to a position corresponding to maximum extension of the dog.
