The American National Standards Committee B107, Socket Wrenches and Drives, under sponsorship by the American Society of Mechanical Engineers, held its organizational meeting on June 28, 1967. Subcommittee 1 on Driving Ends for Portable Hand, Air, and Electric Tools and Subcommittee 3 on Spindle Ends for Portable Air and Electric Tools were subsequently organized. These two subcommittees took over the work that was originally handled by Technical Committee 28 of Standards Committee B5. The data contained in this Standard supersedes that in the B107.4 1982R1988 document. Suggestions for improvement of this Standard will be welcome. They should be sent to The American Society of Mechanical Engineers, Attn Secretary, B 107 Main Committee, 345 East 47th Street, New York, NY 10017. This revision was approved as an American National Standard on October 16, 1995. ... 111 ASME STANDARDS COMMITTEE BI07 Hand Tools and Accessories The following is the roster of the Committee at the time of approval of this Standard.

Other tools not classed as percussion tools belong in this category and may be added by revision or addition through the usual procedure. This Standard includes dimensions and tolerances for both driving and driven elements where such coordination is important and not established by reference to the perti- nent American National Standards. All dimensions are in inches and millimeters. 2 DEFINITIONS tool - as used in this Standard, a portable device for pering a mechanical operation with power from com- pressed air or electricity and hand operated percussion tools - hammers, chisels, scalers, tampers, clay diggers, and rock drills. Percussion tools are ex- cluded from this Standard. rorrnrling values - When the next digit beyond the last digit to be retained is a less than 5, the last digit to be retained is not changed; h 5 or more, the last digit to be retained is increased by one. 3 NORMATIVE REFERENCES Current American National Standards referred to herein include ANSI B7.1- 1988, Safety Requirements for the Use, Care, and Protection of Abrasive Wheels ANSI B92.1-1970 R1982 R1993, Involute Splines and Inspection, Inch Version The values stated in US customary units are to be regarded as the standard.

Example 38.214 5 GAGE USE AND DESIGN The illustrations shown herein are descriptive and not restrictive, and are not intended to preclude the rnanufac- ture of product or gages which are otherwise in accord- ance with this Standard. Manufacturers may use gages with tighter dimensions or tolerances than shown herein to ensure product ac- ceptance. Tolerances on gage dimensions within this Standard represent new, as gage manufactured or purchased gage sizes. The extreme size for all limit GO and NO GO gages shall not exceed the extreme limits of products specified within this Standard. Ail variations manufactur- ing tolerance, calibration error, wear allowance, etc. in the gages, whatever their cause or purpose, shall bring these gages within the extreme limits of this gage size specified within this Standard. Thus a gage which repre- sents a minimum limit may be larger, but never smaller, than the minimum size specified for the product standard; likewise, the gage which represents a maximum limit may be smaller, but never larger, than the maximum size specified for the product standard.
