1.1.1 ASME B18.8.200M covers the complete dimcnsonal and general data lot’ cotter (split) pins recognized as an American National Standard.
1.1.2 Thc inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Con%uliier5 should consult with suppliers concerning the availability of products.
12 Comparison With ISO Standards
The cotter pins in this Standard are similar to the ISO 1234:1997 standard pins. Dimensional differences between this Standard and ISO 1234:1997 are an approximate head height dimension, which is not called for in this Standard, and the wire width dimensions, which are not called out in the ISO Standard. These differences will not aI’Ièct inLerchaneabiIity of cotter pins man ufactured to [he requirements of either
1.3 Dimensions
All dimensions in this Standard are given in millimeters, unless otherwise specified. Dimensions and tolerances re in accordance with ASME Y14,$M.
1.4 Responsibility
The respnnsihk party for the performance of the products within the scope of this Standard is the organization that supplies the components to the purchaser and certifies or represents that the component was manufactured, tested, and inspes.-ted in accordance with this specification and meets all of its requirements.
1.5 Inspection and Quality Assurance
Unless otherwise specified by the purchaser, acceptability shall be based on conformance with the requiremenis specified in ASME B18.l8.IM.
2.5 Hole Location for Type B Pins
2.5.1 Length Between Hole Centers. The siandard nominal lengths. L4, between hole centers are specified in Table 2. and are recommended for use ss ith the standard hole sizes, The tolerances on the length between hole centers are specified in Table 4.
If larger than standard holes are specified. it may be necessary to specify a shorter length. L. between hole centers to maintain adequate material between the edge of the hole and the end of the pin, or to avoid a sharp edge between the countemunk hole and the end chamfer. See Appendix A.
2.5.2 Position of Hole. The axis of the hole shall be within the positional tolerance specified in Table 5 with respect to the axis of the pin, determined over a length from the center of the hole equal to the nominal pin diameter. L). at maximum material condition, and perpendicular to the axis of the pin within 2 deg.
2.6 Material and Hardness
Urthardened ckvis pins shall be furnished unless hardened is specified.
2.6.1 Unhardened Clevis Pins. Unhardcncd steel clcvis pins shall be made from steel with a maximum caxton content of 0.28%. and shall have hardness of
125-245 HV, 119-234 HB. or 69-99 HRB,
2.6.2 Hardened Clevis Pins. Hardened steel clevis pins shall he marked with a capital “H” an one end. Unless otherwise specified by the purehaser. hardened devis pins may be either through hardened or case hardened as follows:
iva) Through hardened clcvis pins shall he made from SAi 52100, AISI 1i52 100, tiNS 0529146. or equivalent alloy steel, and shall have a hardness of 550—650 HV3O. 52-58 HRC. or 517-611 HB,
(b) Case hardened clevis pins shall be made from low carbon steel, such as SAbAISI 1010, UNS 0101(N). or SAEJAISI l2Ll4, UNS 012144. or equivalent, and shall have a surface hardness of 600—700 HV I or 88— 90 IIRISN, and a minimum hardness at case depth of
025-0.4 mm of 550 HVI or 87 HRISN.
2.7 Workmanship
Clevis pins shall be free froni burrs, sharp edges. loose scale, and all other detrimental defects.
