Applies to ferrous and non-ferrous cotter pins in diameters from 1 to 13 mm and lengths from 4 to 125 mm, for general engineering purposes. Shape, dimensions, properties and finish are specified, and recommendations on gauging are included. Guidance on the use of the split cotter pins with ISO metric bolts, screws and clevis pins is given in an appendix, and requirements for humpback split cotter pins used as locking devices for insulated and conductor fittings specified in AS 1154.2, are also given. For inch series see AS B175.

This specification applies to ferrous and non-ferrous split cotter pins in the metric series, in diameters from 1 mm to 13 mm inclusive and lengths from 4 mm to 125 mm inclusive, suitable for general engineering purposes.For the benefit of users, Appendix A sets out recommended combinations of split cotter pins with ISO metric bolts, screws and clevis pins. Associated hole sizes and tolerances are also given. Recommended acceptance gauges and gauge parameters for all types of split cotter pins, except humpback split cotter pins, are given in Appendix B.Similarly, Appendix C gives the requirements of humpback split cotter pins used in insulator and conductor fittings of overhead power lines which are suitable locking devices for pins or bolts specified in AS 1154, Part 2*.
