Abstract
A rivet-setting tool for pull-to-set blind rivets having mandrel-gripping jaws in which the teeth are widely-spaced at a level of only 8-15 teeth per inch; preferably the teeth in each jaw have non-uniform spacing, the spacing between some pairs of teeth being at least twice the spacing of the pairs of teeth in the same jaw; preferably, also, each tooth in one jaw is located directly opposite a tooth in the other jaw.
