under the sponsorship of The American Society of Mechanical Engineers (ASME) It was subsequently reorganized as an ASME Standards Committee, and its title was changed to Hand Tools and Accessories In 996, the Committee’s scope was exp anded to include safety considerations The purpose of ASME B107.17 is to establish final inspection gage sizes and test mandrel sizes for wrench openings, and spark plug wrench openings for inch and metric sizes This Standard does not cover every available size, but only those most commonly manufacturered This Standard may also be used as a guide by state authorities or other regulatory bodies in the formulation of laws or regulations It is also intended for voluntary use by establishments that use or manufacture the instruments covered Changes in the 2015 edition include removal of unused references, corrections to values in Table 4M, and increased significant digits in the plus tolerances in Tables and 4M Members of the Hand Tools Institute Wrenches Standards Committee, through their knowledge and hard work, have been major contributors to the development of the B107 standards Their active efforts in the promotion of these standards are acknowledged and appreciated This revision was approved as an American National Standard on June 19, 2015 iv ASME B107 COMMITTEE Hand Tools and Accessories (The following is the roster of the

Administration v CORRESPONDENCE WITH THE B107 COMMITTEE General ASME Standards are developed and maintained with the intent to represent the consensus of concerned interests As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions or a Case, and attending Committee meetings Correspondence should be addressed to: Secretary, B107 Standards Committee The American Society of Mechanical Engineers Two Park Avenue New York, NY 10016-5990 http://go.asme.org/Inquiry Proposing Revisions Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard Approved revisions will be published periodically The Committee welcomes proposals for revisions to this Standard Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation Proposing a Case Cases may be issued for the purpose of providing alternative rules when justified, to permit early implementation of an approved revision when the need is urgent, or to provide rules not covered by existing provisions Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee Web page Requests for Cases shall provide a Statement of Need and Background Information The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases Requests for Cases should also indicate the applicable edition(s) of the Standard to which the proposed Case applies Interpretations Upon request, the B107 Standards Committee will render an interpretation of any requirement of the Standard Interpretations can only be rendered in response to a written request sent to the Secretary of the B107 Standards Committee at go.asme.org/Inquiry The request for an interpretation should be clear and unambiguous It is further recommended that the inquirer submit his/her request in the following format: Subject: Edition: Question: Cite the applicable paragraph number(s) and the topic of the inquiry Cite the applicable edition of the Standard for which the interpretation is being requested Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation The inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information Request that are not in this format may be rewritten in the appropriate format 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 or Subcommittee ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity Attending Committee Meetings The B107 Standards Committee regularly holds meetings and/ or telephone conferences that are open to the public Persons wishing to attend any meeting and/or telephone conference should contact the Secretary of the B107 Standards Committee Future Committee meeting dates and locations can be found on the Committee Page at go.asme.org/B107committee vi ASME B107.17-2015 GAGES AND MANDRELS FOR WRENCH OPENINGS SCOPE to 56 HRC minimum The hardness shall be tested using procedures outlined in ASTM E18 This Standard establishes final inspection gage sizes and test mandrel sizes for wrench openings and spark plug wrench openings for inch and metric sizes This Standard does not cover every available size, but only those most commonly manufactured 4.2 Gage Use and Design The gages shall be of the sizes and tolerances given in Tables 1, 1M, 2, 2M, 3, and 3M Formulas are provided for sizes not listed The gages shall be used in accordance with accepted practices Manufacturers may use gages with tighter dimensions than those shown herein The size for all limits (GO and NO GO) gages shall not exceed the extreme limits specified herein 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 size specified; likewise, the gage that represents a maximum limit may be smaller, but never larger, than the maximum size specified APPLICATION The gages covered by this Standard shall be used to ensure the manufacture of conforming products in inch and metric sizes REFERENCES The following documents are referenced in this Standard The latest edition shall be used ASTM E1 8, Standard Test Methods for
