This International Standard specifies the thread profile and limits and tolerances for the screw threads used to assemble freewheels on bicycle hubs. It is based on
- the use of the ISO basic thread profile given in ISO 68;
- satisfactory interchangeability with the corresponding British Standard Cycle (B.S.C.) thread; this has required the use of an inch pitch (t.p.i.);
- the use of screw thread tolerance grades and tolerance positions given in ISO 965-1;
- the use of gauges made to ISO 1502.
