ABSTRACT:
A tool for setting threaded bushes has a body portion and a mandrel puller rotatably and slidably mounted in the body portion. A mandrel is fixed to the mandrel puller for movement therewith. The free end portion of the mandrel is screw-threaded for engagement with a threaded bush. Means are provided for sliding the mandrel puller relative to the body portion so that the threaded bush strikes the body portion and is arrested thereby. Further movement of the mandrel puller causes the bush to expand and be set in position. The threaded bush is releasable from the mandrel by rotating the mandrel puller relative to the body portion.
