`,````,``,,,,,```,,,``,``,,,,`-`-`,,`,,`,`,,` - Responding to the request of the U.S War Department, ASA Sectional Committee B27 on Standardization of Plain and Lock Washers was organized August, 1925, with t h e Society of Automotive Engineers and The American Society of Mechanical Engineers a s joint sponsors Since 1950 this committee has been known a s Sectional Committee on Standardization of Washers and Machine Rings Subcommittee on Plain Washers w a s appointed in May, 1928 A proposed standard submitted by t h e subcommittee in October, 1932, w a s revised after circulation for criticism and comment A second revision of t h e proposed standard w a s prepared and distributed in May, 1935 The third and last revision of the proposal w a s referred to t h e sectional cominittee but did not receive the vote necessary for recommending its approval a s an American Standard From 1937 until 1946 the Subcommittee activity was dormant, owing in part to industry preoccupation with the war effort and in part to sectional committee concentration on the development of American Standards for lock washers, - there being some resistance to t h e concurrent development of both projects In 1946 the Subcommittee project w a s reactivated and in December of t h a t year a new proposal for an American Standard w a s approved at a meeting of t h e sectional committee subject to confirming approval by letter ballot vote of the sectional committee A s the proposal received an overwhelming vote of approval in the letter ballot canvass, the sectional committee at a meeting in December, 1948, ordered i t s referral to t h e sponsor societies It was subsequently approved by t h e sponsor societies and by t h e American Standards Association, and officially designated a s an American Standard on August 31, 1949 When the standard was brought up for triennial review it w a s decided to revise it editorially t o include notes covering general applications, material, thickness, and defects which were inadvertently omitted from the 1949 original printing A proposed revision dated l u n e 1952, w a s approved by letter ballot vote of t h e sectional committee, sponsors, and American Standards Association Official designation a s a n American Standard w a s given March 30, 1953 Subsequent to publication of the 1953 issue certain changes and inclusion of an additional series of washers were proposed A proposed revision dated February 1956 was approved by letter ballot vote of t h e Sectional Committee sponsors and t h e American Standards Association Official designation a s an American Standard w a s given on August 5, 1958 Following issuance of the 1958 standard, Subcommittee continued to refine the specifications for plain washers Several meetings resulted in adjustment of t h e tolerances for inside and outside diameters to conform with good Lommercial stamping practices and t h e application of t h e s a m e tolerances to both Type A and Type B w a s h e r s Also, to provide better guidance for users, it was agreed to tabulate the preferred s i z e s of Type A washers separately A proposed revision dated November 1963, was circulated for simultaneous letter ballot approval of Subcommittee and the Sectional Committee on November 18, 1963 A l l disapprovals and comments w e r e resolved by circulation of suggested dispositions on February 12, 1365 The proposal w a s subsequently approved by the sponsor organizations and t h e American Standards Association and granted formal recognition a s an American Standard

dimensions in this standard are given in inches, unless otherwise stated 1.1.2 The inclusion of dimensional data in this standard i s not intended to imply that all of t h e products described herein are production items Consumers are requested to consult with manufacturers concerning l i s t s of stock production sizes 1.4 Materials 1.4.1 Plain washers shall be made of ferrous or non-ferrous metal, plastic or other material a s specified The tolerances indicated in the tables are intended for metal washers only 1.4.2 If hardened washers are required, they are available a s a stamped product without break or gap and a s a flat coiled product with gap narrow enough to prevent tangling Suitable mechanical properties for hardened stamped plain washers are covered by ASTM specification A-325 Applicable properties for plain washers coiled from wire shall be AISI 1060 steel, or equivalent, heat treated to a hardness of Rockwell C 45-53 1.2 Types of Washers 1.2.1 Type A The Type A plain washers were originally developed in a light, medium, heavy, and extra heavy series with proportions that were related to t h e dimensions of bolt heads and nuts principally t o minimize embedding and to aid torquing It i s intended that these series designations should be discontinued and that the washers should be identified by their nominal dimensions Washer selection should be made peferably from the preferred s i z e s shown in Table 1A In the event t h e desired Type A washer i s not listed in Table l A , reference may be made to Table 1B 1.5 Quality Washers shall be free from burrs, loose scale, sharp edges and all other defects that might affect their serviceability 1.2.2 Type B The Type B plain washers are available in a narrow, regular and wide series with proportions designed to fulfill the customary purpose of distributing load over larger areas of lower strength materi als Suitable washer selection can be made by referring in Table to t h e nominal screw or bolt s i z e and selecting the appropriate width series for the application 1.6 Terminology For definitions of t e r m s relating to washersor features thereof used in this standard, refer to the American Standard Glossary of Terms for Mechanical Fasteners, ASA B18.12 `,````,``,,,,,```,,,``,``,,,,`-`-`,,`,,`,`,,` - Copyright ASME International Provided by IHS under license with
