Specifies the thread profile and limits and tolerances for the screw threads used to assemble freewheels on bicycle hubs. Based on the use of the ISO basic thread profile, satisfactory interchangeability with the corresponding B.S.C. thread, the use of screw thread tolerance grades and tolerance positions and the use of gauges made to ISO 1502.
