Drives, under sponsorship by the American Society of Mechanical Engineers, held its organizational meeting on June 28, 1967 Subcommittee on Driving Ends for Portable Hand, Air, and Electric Tools and Subcommittee 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 supersede that in the B107.4 1982(R1988) document The Committee subsequently undertook to task to revise the 1982 standard The work was completed, and the revised standard was approved as an American National Standard on October 16, 1995 The format of this Standard is in accordance with The ASME Codes and Standards Writing Guide 2000 Requests for interpretations, and suggestions for the improvement of this Standard, should be addressed to The American Society of Mechanical Engineers, Secretary, B107 Committee, Three Park Avenue, New York, NY 10016-5990 The requirements of this Standard become effective at the time of publication ASME B107.42005 was approved as an American National Standard on March 14, 2005 v ASME B107

however, they should not contain proprietary names or information Requests that are not in this format will be rewritten by the Committee prior to being answered, which may inadvertently change the intent of the original request ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity Attending Committee Meetings The B107 Standards Committee holds meetings or telephone conferences, which are open to the public Persons wishing to attend any meeting should contact the Secretary of the B107 Standards Committee or check our Web site at http://www.asme org/codes/ vii viii ASME B107.4-2005 DRIVING AND SPINDLE ENDS FOR PORTABLE HAND, IMPACT, AIR, AND ELECTRIC TOOLS (PERCUSSION TOOLS EXCLUDED) ANSI B92.1-1996, Involute Splines and Inspection Publisher: American National Standards Institute (ANSI), 25 West 43rd Street, New York, NY 10036 ISO 117-1:1996, Assembly tools for screws and nuts — Driving squares — Part 1: Driving squares for hand socket tools ISO 1174-2:1996, Assembly tools for screws and nuts — Driving squares — Part 2: Driving squares for power socket tools Publisher: International Organization for Standardization (ISO), rue de Varembé, Case Postale 56, CH1211 Genève 20, Switzerland/Suisse SCOPE This Standard applies to portable power tools for drilling, grinding, polishing, sawing, and driving threaded fasteners and hand tools for driving threaded fasteners 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 pertinent American National Standards All dimensions are in inches and millimeters.1 ISO COMPATIBILITY Italicization and bold type indicate ISO compatibility DEFINITIONS EXAMPLE: (38.214) percussion tools: hammers, chisels, scalers, tampers, clay diggers, and rock drills Percussion tools are excluded from this Standard GAGE USE AND DESIGN rounding 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 (b) or more, the last digit to be retained is increased by one The illustrations shown herein are descriptive, not restrictive, and not intended to preclude the manufacturer of products or gages which are otherwise in accordance with this Standard Manufacturers may use gages with tighter dimensions or tolerances than shown herein to ensure product acceptance Tolerances on gage dimensions within the Standard represent new 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 the Standard All variations (manufacturing 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 that represents a minimum limit may be larger, but never smaller, than the minimum specified for the product standard; likewise, the gage that represents a maximum limit may be smaller, but never larger, than the maximum size specified for the product standard tool: as used in this Standard, a portable device for performing a mechanical operation with power from compressed air or electricity and hand operated NORMATIVE REFERENCES The following is a list of publications referenced in this Standard ANSI B1.1-1989R01 Ed, Unified Inch Screw Threads (UN and UNR Thread Form) ANSI B7.1-2000, Safety Requirements for the Use, Care, and Protection of Abrasive Wheels The values stated in U.S customary units are to be regarded as the standard DRIVING AND SPINDLE ENDS FOR PORTABLE HAND, IMPACT, AIR, AND ELECTRIC TOOLS ASME B107.4-2005 Table 10 Square Drive Gage Specifications for Hand, Power, and Impact Wrenches—External End, in C, 0.000 0.001 in mm Am, 0.0000 0.0002, All Designs 1/ 3/ 1/ 6.3 10.0 12.5 0.252 0.377 0.502 0.3300 0.5000 0.6650 0.312 0.438 0.625 0.516 0.653 0.265 0.406 0.531 0.482 0.619 0.312 0.438 0.625 0.2467 0.3717 0.4967 5/ 3/ 16.0 20.0 25.0 0.627 0.752 1.002 0.8340 1.0000 1.3400 0.656 0.938 1.125 0.794 0.915 1.170 0.594 0.750 1.000 0.760 0.875 1.130 0.656 0.938 1.125 0.6217 0.7467 0.9965 11/2 21/2 31/2 40.0 63.0 1.503 2.500 3.500 1.9680 3.3440 4.6870 1.625 2.265 3.265 1.562 2.234 3.234 1.625 2.265 3.265 1.4975 2.4845 3.4845 Drive Size B, 0.0002 0.0002, All Designs Designs A, B, and D D, 0.001 0.000 Design C Designs A, B, and D Design C G Min., Designs A, B, and D Em, 0.0002 0.0000, All Designs GENERAL NOTES: (a) NO GO gage must be used by rotating gage 90 deg to check both sets of across flat dimensions (b) Gage tolerances are tool makers’ gage manufacturing tolerances Table 10M Square Drive Gage Specifications for Hand, Power, and Impact Wrenches—External End, mm D, 0.03 0.00 C, 0.00 0.03 mm in Am, 0.000 0.005, All Designs 6.3 10.0 12.5 1/ 3/ 1/ 6.401 9.576 12.751 8.38 12.70 16.89 7.92 11.13 15.88 13.11 16.59 6.73 10.31 13.49 12.24 15.72 7.92 11.13 15.88 6.266 9.441 12.616 16.0 20.0 25.0 5/ 3/ 15.926 19.101 25.451 21.18 25.40 34.04 16.66 23.83 28.58 20.17 23.24 29.72 15.09 19.05 25.40 19.30 22.23 28.70 16.66 23.83 28.58 15.791 18.966 25.311 40.0 63.0 11/2 21/2 31/2 38.176 63.500 88.900 49.99 84.94 119.05 41.28 57.53 82.93 39.67 56.74 82.14 41.28 57.53 82.93 38.037 63.106 88.506 Drive Size B, 0.005 0.005, All Designs Designs A, B, and D Design C Designs A, B, and D Design C G Min., Designs A, B, and D Em, 0.005 0.000, All Designs GENERAL NOTES: (a) NO GO gage must be used by rotating gage 90 deg to check both sets of across flat dimensions (b) Gage tolerances are tool makers’ gage manufacturing tolerances 11
