Since 1950 this committee has been known a s Sectional Committee on Standard- ization of Washers and Machine Rings. Subcommittee 1 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 com- inittee but did not receive the vote necessary for recommending its approval a s an American Standard. From 1937 until 1946 the Subcommittee 1 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 1 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 sec- tional 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 to 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 the sectional committee, sponsors, and American Standards Association. Official designation as 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. 1 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 izes of Type A washers separately. A proposed revision dated November 1963, was circulated for simul- taneous letter ballot approval of Subcommittee 1 and the Sectional Committee on November 18, 1963. A l l disapprovals and comments were resolved by circulation of suggested dis- positions 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 on September 20, 1965. Following issuance of the 1958 standard, Subcommittee 3 Copyright ASME International Provided by IHS under license with ASME Licensee=JGC CORP/5959408001 Not for Resale, 11/14/2005 21:03:33 MSTNo reproduction or networking permitted without license from IHS - - ` , ` ` ` ` , ` , ` ` , ` , ` , , ` ` , ` ` , , ` ` , , - ` - ` , , ` , , ` , ` , , ` - - - 627 Standardization of Washers and Machine Rings R.

Consumers are requested to consult with manu- facturers concerning l is ts of stock production sizes. 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 the dimensions of bolt heads and nuts principally to 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 pef- erably from the preferred s izes shown in Table 1A. In the event the desired Type A washer i s not listed in Table l A , reference may be made to Table 1B. 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 selec- tion can be made by referring in Table 2 to the nominal screw or bolt s ize and selecting the appropriate width series for the application. 1.3 Dimensions All dimensions in this standard are given in inches, unless otherwise stated. 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 as 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 Rock- well C 45-53. 1.5 Quality Washers shall be free from burrs, loose scale, sharp edges and all other defects that might affect their serviceability. 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. 5 Copyright ASME International Provided by IHS under license with ASME Licensee=JGC CORP/5959408001 Not for Resale, 11/14/2005 21:03:33 MSTNo reproduction or networking permitted without license from IHS --`,````,`,``,`,`,,``,``,,``,,-`-`,,`,,`,`,,`--- ~~ ~ - S T D - A S M E B18.22.1-ENGL L9b5 = 0759b70 Ob20882 bbT = AMERICAN STANDARD Table 1A Nominal Washer Size*** - - - No. 6 No. 8 No. 10 %6 No. 12 !4 !4 26 36 % 4 6 % !4 $ 4 6 :46 i s k 4 % % ::: :g 1 1 1% 1% 1% 1% 1 % 2 2% 2% 2% 3 1% 1% 1% 1% - - - 0.138 0.164 0.190 0.188 0.216 0.250 0.250 0.312 0.312 0.375 0.375 0.438 0.438 0.500 0.500 0.562 0.562 0.625 0.625 0.750 0.750 0.875 0.875 1.000 1 .o00 1.125 1.125 1.250 1.250 1.375 1.375 1.500 1.500 1.625 1.750 1.875 2.000 2.250 2.500 2.750 3.000 N W N W N W N W N W N W N W N W N W N W N W N W N W N W Dimensions of Preferred Sizes of Type A Plain Washers** Ins ide Diameter B a s i c 0.078 0.094 0.125 0.156 0.188 0.213 0.250 0.250 0.281 0.312 0.344 0.375 0.406 0.438 0.469 0.500 0.531 0.562 0.594 0.62 5 0.656 0.688 0.812 0.812 0.738 0.938 1.062 1.062 1.250 1.250 1.375 1.375 1.500 1.500 1.625 1.625 1.750 1.875 2.000 2.125 2.375 2.625 2.87 5 3.125 A Tole rance P l u s 0.000 0.000 0.008 0.008 0.008 0.008 0.015 0.015 0.015 0.015 0.015 0.015 0.0 15 0.0 15 0.015 0.0 15 0.015 0.01 5 0.015 0.01 5 0.030 0.030 0.030 0.030 0.030 3.030 0.030 3.030 3.030 3.030 3.030 3.030 3.030 1.045 3.030 3.045 3.045 3.045 3.045 3.045 5.045 3.045 3.065 3.065 Minus 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0,005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.007 0.007 0.007 0,007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 D.O1O 0.007 0.010 0.010 0.010 3.010 0.010 0.010 0.010 0.0 10 0.0 10 Outs ide Diameter B Basic 0.188 0.250 0.312 0.375 0.438 0.500 0.562 0.562 0.625 0.734 0.688 0.875 0.812 1 .o00 0.922 1.250 1.062 1.375 1.156’ 1.463. 1.312 1.750 1.469 2.000 1.750 2.250 2.000 2.500 2.250 2.750 2.500 3.000 2.750 3.250 3.000 3.500 3.750 4.000 4.250 4.500 4.750 5.000 5.250 5.500 Tole rance Plus 0.000 0.000 O .O 08 0.015 0.015 0.015 0.01s 0.015 0.015 0.015 0.015 0.0 30 0.015 O .O30 0.015 O .O 30 O .O 30 0.030 0.030 0.030 0.030 0.030 0.030 0.030 0.030 0.030 0.030 0.030 0.030 O .O 30 0.030 0.030 0.030 0.043 0.030 O .O4 5 O .O4 5 0.045 0.045 0.045 0.045 O .O4 5 0.065 0.065 - Minus 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.005 0.007 0.007 0,007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 0.007 O .O 07 0.007 0.007 0.0 10 0.007 0.010 0.010 0.010 0.010 0.010 0.010 0.010 0.010 0.010 B a s i c 0.020 0.020 0.032 0.049 0.047 0.049 0.049 0.065 0.065 0.065 0.065 0.083 0.065 0.083 0.065 0.083 0.095 0.103 0.035 0.103 0.095 0.134 0.134 O. 148 0.134 0.165 0.1 34 0.165 O. 134 0.165 0.165 0.165 0.165 0.1 80 0.165 0.180 0.1 80 0.180 0.180 0.180 0.220 0.238 0.259 0.284 T h i c k n e s s C Max 0.025 0.025 0.040 0.065 0.065 0.065 0.065 0.080 0.080 0.080 0.080 O. 104 0.080 0.104 0.080 O. 104 0.121 0.132 0.121 0.132 0.121 0.160 O. 160 0.177 O. 160 0.192 0.160 0.192 O. 160 0.192 0.192 0.192 0.192 0.213 0.132 0.2 13 0.213 0.213 0.213 0.2 13 0.248 0.280 0.310 0.327 Min 0.0 16 0.0 16 0.025 0.036 0.036 0,036 0.036 0.051 0.051 0.051 0.051 0.064 0.051 0.064 0.051 0.064 0.074 0.086 0.074 0.086 0.074 o. 108 0.108 0.122 0.108 O. 136 0.108 O. 136 o. 108 O. 136 0.136 0.136 0.136 0.153 0.136 0.153 0.153 0.153 0.153 0.153 0.193 0.210 0.228 0.249 -- *The 0.734 in., 1.156 in., and 1.469 in. outside diameteti avoid washers which could be used in coin operated devices .
