ABSTRACT:
An adjustable and releasable fastener for a pivoting hand tool includes a first bushing and a second bushing which are press fit in respective tool elements, the second bushing extending into a hole in the first bushing to form a pivot bearing. The first bushing includes a cap with a recess having a slotted opening connecting to the hole in the first bushing. A bolt is extends through the first and second bushings, with a bolt head disposed in the recess. A nut is fastened to a threaded end on the second bushing side. The nut can be tightened or loosened to adjust the tension on the bolt. The bolt head is shaped to allow it to pass through the slotted opening in the first bushing when the tool elements are pivoted beyond an operating range, permitting quick release of the tool elements.
