14、Standards Committee (later the American StandardsAssociation, then the United States of America Standards Institute, and as of October 6, 1969,the American National Standards Institute, Inc.), with the Society of Automotive Engineers andthe American Society of Mechanical Engineers as joint sponsors.

15、Subcommittee 11 was established in 1953 and charged with the responsibility for the develop-ment of standards for semi-tubular rivets, full tubular rivets, and split rivets. In the years between1953 and 1962, meetings of the subcommittee were held and numerous attempts were made toarrive at suitable

16、 standards. However, problems stemming from the wide variety of these productsand their applications continually prevented the Subcommittee from reaching a consensus.At a meeting held on October 2, 1962, the Subcommittee agreed to limit the scope of thestandard to only those products suitable for ge

17、neral purpose applications. Thorough cooperationbetween the user and manufacturing members culminated in the development of a draft proposalwhich was approved by letter ballot of Subcommittee 11 on August 6, 1964. The proposedstandard was circulated for letter ballot approval of the B18 Committee on

18、 May 13, 1965. Followingfavorable action by this committee and the sponsor organizations, the proposal was approvedby the United States of America Standards Institute and designated a USA Standard onSeptember 2, 1966.The previous edition incorporated the addition of nominal sizes to dimensional tabl

19、es andstandard designations for the various products. Also, numerous editorial refinements were devel-oped and approved by Subcommittee 7 in April 1970. Subsequent to letter ballot approval bythe B18 Committee and the sponsors, this proposal was submitted to the American NationalStandards Institute

20、for designation as an American National Standard. This was granted onJuly 28, 1972 and last reaffirmed without change in 2005.This edition was balloted and approved by the B18 Standards Committee and B18 Subcommittee2 on December 28, 2006. The proposal was submitted to the American National Standard

21、s Institute(ANSI) and designated as an American National Standard on March 7, 2007.ivASME B18 COMMITTEEStandardization of Bolts, Nuts, Rivets, Screws,Washers, and Similar Fasteners(The following is the roster of the Committee at the time of approval of this Standard.)STANDARDS COMMITTEE OFFICERSD.

26、general anddimensional data for semi-tubular rivets, full tubularrivets, split rivets, and rivet caps for use in general pur-pose applications. The products described are suitablefor joining metallic and nonmetallic materials or combi-nations thereof. It should be noted that while these prod-ucts ar

27、e suitable for general purpose assembly, otherspecial purpose types are available to satisfy particularrequirements and manufacturers should be consultedfor special requirements.1.1.2 The inclusion of dimensional data in thisStandard is not intended to imply that all of the productsdescribed are sto

28、ck production sizes. Consumers arerequested to consult with suppliers concerning availabil-ity of products.1.2 Types of RivetsThe rivets specified in this Standard are included inparas. 1.2.1 through 1.2.31.2.1 Semi-Tubular Rivets. The semi-tubular rivetsare available in the head styles listed below

29、 and shallhave straight holes, Type S, normally produced byextruding or drilling; or tapered holes, Type T, normallyproduced by swaging.(a) oval head semi-tubular rivets (see Table 1)(b) truss head semi-tubular rivets (see Table 2)(c) 150-deg flat countersunk head semi-tubular rivets(see Table 3)(d)

30、 150-deg large flat countersunk head semi-tubularrivets (see Table 4)(e) 120-deg flat countersunk head semi-tubular rivets(see Table 5)1.2.2 Full Tubular Rivets. The full tubular rivetsare available in the head styles listed below and shallnormally have straight holes produced by extruding ordrillin

Box C700, West Conshohocken, PA,19428-29592 GENERAL DATA FOR SEMI-TUBULAR AND FULLTUBULAR RIVETS2.1 Heads2.1.1 Because the heads of these rivets are notmachined or trim

38、med, the circumference may be some-what irregular and edges may be rounded or flat.2.1.2 The bearing surface of oval and truss headrivets shall be perpendicular to the axis of the rivetshank within 2 deg.2.1.3 The rivet head and the rivet shank shall beconcentric within 11% of the nominal shank diam

39、eteron the basis of full indicator movement (FIM).2.2 Underhead FilletsOval and truss head rivets shall be furnished with adefinite fillet under the head; however, the radius of filletshall not exceed the values specified in the dimensionaltables.2.3 Length2.3.1 Measurement. The length of oval and t

40、russhead rivets shall be measured, parallel to the axis ofrivet, from the underside of the head to the extremeend. The length of flat countersunk head rivets shall bemeasured, parallel to the axis of rivet, from the junctureof the conical underside of head with rivet shank to theextreme end, except

41、for the 120-deg flat countersunkhead rivets in Table 5, on which the length shall bemeasured from the top of the head to the extreme end.2.3.2 Length Increments. The minimum lengthsand increments applicable to longer lengths shall be asspecified in Table 10.2.3.3 Tolerance on Length. The tolerance o

42、n lengthof rivets shall be as specified in Table 10.2.4 Hole Depth2.4.1 Hole depth shall be measured parallel to theaxis of the rivet from the extreme end of the rivet to theintersection of the diameter of the hole with the contourat the bottom of the hole. The hole depth to the extremepoint on the

43、bottom contour of the hole shall not begreater than the shank length of the rivet.2.4.2 The tolerance on hole depth shall be the sameas the tolerance on length of the rivet.22.5 MaterialSemi-tubular and full tubular rivets shall be madefrom low carbon steel (0.1% carbon or less)(UNS G10050), commerc

44、ial yellow brass (UNS C26800),copper (UNS C14700), aluminum (UNS A95052), orother materials as agreed upon between the manufac-turer and the purchaser.2.6 FinishUnless otherwise specified, rivets shall be suppliedwith a natural (as processed) finish, unplated oruncoated. Rivets may be furnished plai

45、n (bare metal)or with a protective coating (electrodeposited platingand/or chemical conversion coating) as specified by theuser. All rivets shall be provided with a supplementarylubricant if necessary to meet the stated performancerequirements without galling. The lubricant shall beclean and dry to

46、the touch, shall not be irritating tonormal skin, nor emit an unpleasant odor during rivetassembly. The performance of rivets that are furnishedwith a protective coating shall not deteriorate when therivets are stored indoors for a period of 6 months. Incases where rivets are given a protective coat

47、ing or arecleaned following delivery to the purchaser, the rivetproducer shall not be held responsible for failure of therivet to meet dimensional, mechanical, or performancerequirements traceable to plating, coating, or cleaningpractice. Lubrication (e.g., waxing) may improve thesetting of the rive

48、t.NOTE: Nickel and chromium finishes are very hard and, there-fore, will have a tendency to flake off the end of the rivet whenit is set by the user.2.7 WorkmanshipThe rivets shall be free from all burrs, seams, or otherimperfections that might impair their usability. Rivetsare not machined or trimm

49、ed, and unevenness of thetubular end shall not be such that the usability of therivet shall be impaired, when clinched with properlyaligned, appropriate setting tools.2.8 Designation2.8.1 Semi-tubular and full tubular rivets shall bedesignated by the following data in the sequence shown:(a) nominal size(b) length (fraction or decimal equivalent)(c) product name(d) material(e) protective finish, if requiredEXAMPLES:(1) ASME B18.7, 146 500 Semi-Tubular Rivet, Oval Head, Steel,Zinc-Plated(2) ASME B18.7, 188 34Full Tubular Rivet, Flat, CountersunkHead, Steel2.8.2 For a recommended par
