1 SCOPE This Standard provides performance and safety requirements for combination wrenches. Except where indicated, these requirements also apply to wrenches described in B107.9, Box Wrenches, Double Head; B107.39, Open End Wrenches, Double Head; and B107.40, Wrenches, Flare Nut. Inclusion of dimensional data in this Standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested toconsultwithmanufacturers concerninglists of stock production sizes. 2 CLASSIFICATION (a) B107.6 — Combination wrench, open end and 15 deg offset box opening (b) B107.9 — Box wrench, double head Type I: 15 deg offset each end Type II: modified offset each end Type III: deep offset each end (c) B107.39 — Open end wrench, double head Type I: engineer’s wrench, 15 deg angle Type II: Class 1: 30 deg and 60 deg angle wrench Class 2: 15 deg and 60 deg ignition wrench Class 3: 15 deg and 60 deg angle wrench Type III: tappet wrench, 15 deg angle (d) B107.40 — Flare nut wrench Type I: double head Type II: combination, open end and 15 deg offset slotted box end 3 REFERENCES The following is a list of publications referenced in this Standard.

Inch table values are in inches unless otherwise specified. Metric table values are in millimeters unless otherwise specified. Wrenches shall pass applicable tests in section 5. Conformance with marking and other requirements not determined by test shall be verified by visual examination.
4.1 Design Wrenches shall provide a well proportioned comfort- able handgrip and be similar to the figure to which reference is made. The engaging surfaces of the wrench openings shall be finished in a smooth and well-defined manner. Wrenches that have a box end design shall be chamfered on at least one side to provide a lead for the working surfaces. The tips of all open ends shall have no burrs. 4.1.1 Wrench Openings. Wrench openings shall be such as to ensure acceptance when gaged with gages conforming to ASME B107.17M, and shall conform to one of the following wrenching opening designs: (a) Standard Single or Double Hexagon Configuration. This design consists of a simple geometric single (6-point) hexagon or a double (12-point) hexagon config- uration having an across-flats and an across-corner shape for fitting with hexagon fasteners.
Marking shall be as permanent as the normal life expectancy of the wrench to which it is applied (provid- ing the marked surface has not been subjected to a fret- ting or abrading action) and be capable of withstanding the cleaning procedures normally experienced during its intended use. The marked area of the wrench may be exempt from the corrosion test in para. 5.3.4 when mutually agreed upon by the manufacturer and customer. 4.4 Hardness Wrenches shall be heat treated to 38 HRC to 55 HRC when tested as specified in para. 5.1. 4.5 Proof Torque When tested as specified, wrenches shall withstand the proof torque specified in the applicable tables with- out failure or permanent deformation (set) that might affect the durability or serviceability of the wrenches. See Tables 1 and 1M. 4.6 Finish 4.6.1 Surface Finish (See Fig. 2).
