Abstract
An open end wrench head including first and second jaws that are adapted to engage a workpiece located in a hard-to-reach area. The jaws can include a chamfered portion on the end of the jaws that allows the wrench to be presented at an angle to the workpiece and still maximize the engagement area between the wrench and the workpiece.
Claims18
A wrench head having a wrench head thickness comprising:
- first and second opposing jaws having a first surface and a second surface opposite the first surface;
- a receiving area defined by the first and second jaws and adapted to receive a workpiece that is adapted to abut a working surface, the receiving area having an open end, a rear portion, and a receiving area thickness;
- and
- a chamfer provided on the first surface, proximate to the open end and extending along the first surface and terminating between the open end and the rear end, the chamfer being sized and shaped to be disposed substantially flush against the working surface therein receiving the workpiece and to maintain the receiving area thickness constant relative to the workpiece.

A wrench comprising:
- a handle;
- a head having a head thickness coupled to the handle and adapted to engage a workpiece, the workpiece adapted to engage a working surface, the head including:
- first and second opposing jaws having a first surface and a second surface opposite the first surface;
- a receiving area defined by the first and second jaws and having an open end, a rear portion, and a receiving area thickness;
- and
- a chamfer provided on the first surface, proximate to the open end and extending along the first surface and terminating between the open end and the rear end, the chamfer being sized and shaped to be disposed substantially flush against the working surface therein receiving the workpiece and to maintain the receiving area thickness constant relative to the workpiece.

A combination comprising:
- a workpiece;
- a handle;
- and
- a head having a head thickness coupled to the handle and adapted to engage a workpiece, the workpiece adapted to engage a working surface, the head including:
- first and second opposing jaws having a first surface and a second surface opposite the first surface;
- a receiving area defined by the first and second jaws and having an open end, a rear portion, and a receiving area thickness;
- and
- a chamfer provided on the first surface, proximate to the open end and extending along the first surface and terminating between the open end and the rear end, the chamfer being sized and shaped to be disposed substantially flush against the working surface therein receiving the workpiece and to maintain the receiving area thickness constant relative to the workpiece.
