1.1.1 ASME B18.7 covers complete general and dimensional data for semi-tubular rivets, full tubular rivets, split rivets, and rivet caps for use in general purpose applications. The products described are suitable for joining metallic and nonmetallic materials or combinations thereof. It should be noted that while these products are suitable for general purpose assemhh other special purpose types are available to satisfy particular requirements and manufacturers should be consulted for special requirements.
1.1.2 The inclusion of dimensional data in this Standard is not intended to imply that all of the products described are stock production sizes. Consumers are requested to consult with suppliers concerning availabilitv of products.
1.2 Types of Rivets
The rivets specified in this Standard are included in paras. 1.21 through 1.2.3
1.2.1 SemI-Tubular Rivets. The semi-tubular rivets are available in the head styles listed below and shall have straight holes, Type S. normally produced by extruding or drilling; or tapered holes, Type T, normally produced 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) 150-deg large flat countersunk head semi-tubular rivets (see Table 4)
(e) 120-deg flat countersunk head semi-tubular rivets (see Table 5)
1.2.2 Full Tubular Rivets. The full tubular rivets are available in the head styles listed below and shall normally have straight holes produced by extruding or drilling.
(a) oval head full tubular rivets (see Table 6)
(b) truss head full tubular rivets (see Table 6)
(c) flat-countersunk head full tubular rivets (see Table 6)
1.2.3 Split Rivets. The split rivets covered herein consist of the following head styles:
3.6 Finish
Unless otherwise specified, rivets shall be supplied with a natural (as processed) finish, unplated or uncoated. Rivets may be furnished plain (bare metal) or with a protective coating (electrodeposited plating and/or chemical conversion coating) as specified by the user. All rivets shall be provided with a supplementary lubricant if necessary to meet the stated performance requirements without galling. The lubricant shall be clean and dry to the touch, shall not be irritating to normal skin, nor emit an unpleasant odor during rivet assembly. The performance of rivets that are furnished with a protective coating shall not deteriorate when the rivets are stored indoors for a period of (, months. In cases where rivets are given a protective coating or are cleaned following delivery to the purchaser, the rivet producer shall not be held responsible for failure of the rivet to meet dimensional, mechanical, or performance requirements traceable to plating, coating, or cleaning practice. Lubrication (e.g., waxing) may improve the setting of the rivet.
NOTE: Nickel and chromium finishes are very hard, and therefore will have a tendency to Fbke off the end of the rivet when it is set by the user.
3.7 Workmanship
The rivets shall be free from all burrs, seams, or other imperfections that might impair their usability. Rivets are not machined or trimmed, and unevenness of the end shall not be such that the usability of the rivet shall be impaired, when clinched with properly aligned, appropriate setting tools.
3.8 Designation
Split rivets shall be designated 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 required.
