T

5、here may also be supplemental group instructions in regard to use of metric standards that should be taken into account. In formulating this standard for metric split pins, considerable investigation was devoted to an effort to establish interchangeability with the inch series pins in order to avoid

6、 the creation of separate part numbers, records, inventories, etc. However, significant dimensional differences in most sizes, primarily in head dimensions and recommended hole sizes, preclude this possibility. This specification contains the essentials of the following standards: International Orga

7、nization for Standardization: ISO R 1234 Association Francaise de Normalisation: NF E27-487 British Standards Institute: BS 1574 Deutsche Normen: DIN 94 Standards Association of Australia: AS 1236 The inclusion of dimensional data is not intended to imply that all the pins described are stock produc

8、tion sizes. Inch series split (cotter) pins may be found in MPAPS S-J-1.101-GS/PL. 2.0 DESIGN CONSIDERATION: Split pins are normally used to position and lock parts in alignment. They are also used as locking devices for other features such as clevis pins, shafts, threaded rods, etc. The optimum usa

9、ge of split pins is to lock slotted nuts. In these applications, the pin should be of sufficient length to provide a minimum of 6 mm protrusion of the longer leg beyond the nut flat. This allows adequate grip for bending the pin legs at installation. 3.0 METRIC-INCH RELATED SIZES: During the inch to

10、 metric design conversion period, the following chart of related sizes may be of value for handy reference. This information is not to be considered as recommended size substitutions but only as a means of quickly determining approximate dimensional equivalents. NUMBER: MPAPS S-JM-1.101-GS/PL TITLE:
