A tool (10) for setting rivet nuts (45) in which the non-rotatable collet (23) moved by handles (11,12) and receives in threaded engagement the mandrel holder (29) so that the mandrel holder (29) is axially adjustable with respect to the collet (23). Mandrels (36) are readily inserted in, secured to

A tool (10) for setting rivet nuts (45) in which the non-rotatable collet (23) moved by handles (11,12) and receives in threaded engagement the mandrel holder (29) so that the mandrel holder (29) is axially adjustable with respect to the collet (23). Mandrels (36) are readily inserted in, secured to and removed from the mandrel holder (29) so that a selected mandrel (36) can be used for each type of rivet to be set against selected anvils (18, 20 and 62). Tool (10) is adjustable in various ways to ease placing the rivet (45) on the mandrel (36), affecting adjustment of the position of the rivet nut (45) vis-a-vis the anvil (18, 20 and 62) for a proper and effective pulling stroke and adjusting the travel of the collet during the stroke.

A hand-held tool adaptable for setting a plurality of types of headed fasteners each of which is set by pulling the fastener to deform the head comprising (a) a housing including an anvil; (b) a cavity in the housing; (c) first and second reciprocatable non-rotatable puller means for selective mount

A hand-held tool adaptable for setting a plurality of types of headed fasteners each of which is set by pulling the fastener to deform the head comprising (a) a housing including an anvil; (b) a cavity in the housing; (c) first and second reciprocatable non-rotatable puller means for selective mounting in the cavity; each puller means capable of pulling at least one type of fastener; (d) a first handle fixed to the housing; (e) a second handle slidably engageable with each puller means and pivotably mounted on the housing to move each puller means reciprocally in the housing over a fixed range by manipulation of the handles toward and away from one another; (f) the first puller means having an internal bore throughout the length of the puller means and a mandrel holder threadedly engageable in the bore of such puller means so that the mandrel holder is movable axially further in and axially further out of the puller means; such mandrel holder having a lower threaded stem portion extending from the cavity of the housing for threaded engagement with the fastener; and (g) the second puller means adapted to be substituted in the housing cavity for the first puller means; said second puller means having jaw means to releasably grip an unthreaded fastener stem.
