1.1.1 This Standard covers the complete dimensional and general data for cotter (split) pins recognized as an American National Standard.
1.1.2 The inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Consumers should consult with suppliers concerning the availability of products.
1.2 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 affect interchangeability of cotter pins manufactured to the requirements of either.
1.3 Dimensions All dimensions in this Standard are given in milimeters, unless otherwise specifed. Dimensions and toler- ances are in accordance with ASME Y14.5M.
1.4 Responsibility The responsible party for the performance of the products within the scope of this Standard is the organization that supplies the components to the pur- chaser and certifies or represents that the component was manufactured, tested, and inspected in accordance with this specification and meets all of its requirements. 1.5 Inspection and Quality Assurance Unless otherwise specified by the purchaser, accept- ability shall be based on conformance with the requirements specified in ASME B18. 18.1M.
1.6 Terminology For definitions of terms relating to pins or features thereof used in this Standard, refer to ASME B18.12.

2 GENERAL DATA
2.1 Application The cotter pins specifed are intended for use in pinned bolt and nut assemblies or other type of free fitting pinned assemblies in general applications.
2.2 Head Design A degree of leeway shall be permissible in the design of the head provided; however, the minimum outside diameter is maintained as specified in Table 2.
2.3 Length
2.3.1 Measurement. The length of pin, L, shall be measured, parallel to the axis of the pin, from the plane of contact of a gage with the head of the pin to the end of the prong or pin as depicted in the ilustrations for the respective point types (sce Fig. 1). The gage shall have a hole equal to the specified gage hole diameter within a tolerance of +0.03 mm (see Table 2). The permissible break or rounding at the gaging edges of gaging holes shall not exceed 0.13 mm. The pin shall be inserted into the gage with finger pressure (force not to exceed 2.2 N). Where pins having point types other than those illustrated herein are gaged, the length, L, shall be measured from the plane of contact of the gage with the end of the shortest prong.
2.3.2 Tolerance on Length. The tolerance on length of cotter pins shall be as specified in Table l.
2.3.3 Preferred Lengths. Table 3 depicts the pre- ferred sizes and lengths of pins that are normally available. Other sizes and lengths are produced, as required by the purchaser.
