Abstract
A hand tool includes a first jaw, a first handle fixed to the first jaw, a second jaw, and a second handle pivotally coupled to the second jaw, a link member, and an adjustment member. The adjustment member is operable to axially move a first end of the link member to vary a distance between the first and second jaws. The adjustment member includes an engagement surface engageable with the first end of the link member, a shank in threaded engagement with a bore in the first handle, and a flange extending from the shank opposite the engagement portion. The flange includes a first side, a second side opposite the first side, and an elongate opening extending through the first and second sides.

A hand tool comprising:
- a first assembly including a first jaw and a first handle fixed to the first jaw, the first handle having a bore at an end opposite the first jaw;
- a second assembly pivotally coupled to the first assembly, the second assembly including a second jaw and a second handle pivotally coupled to the second jaw;
- a link member having a first end axially movable along the first assembly and a second end pivotally coupled to the second assembly;
- and
- an adjustment member operable to axially move the first end of the link member along the first assembly to vary a distance between the first and second jaws, the adjustment member including:
- an engagement surface engageable with the first end of the link member;
- a shank in threaded engagement with the bore, the shank defining a longitudinal axis;
- and
- a flange extending from the shank opposite the engagement surface, the flange including:
- a first side;
- a second side opposite the first side;
- and
- an elongate opening extending through the first and second sides;
- wherein the elongate opening defines a major dimension coaxial with the longitudinal axis and a minor dimension perpendicular to the longitudinal axis;
- wherein the major dimension is greater than the minor dimension;
- wherein the minor dimension is between 6 millimeters and 12 millimeters;
- wherein the major dimension is between 8 millimeters and 16 millimeters;
- and
- wherein a ratio of the minor dimension to the major dimension is between 0.4 and 0.9.
