JIS B 2401
Include the series prefix. P and G designations identify different size series.
Search JIS dimensions ↗ISO 3601-1
Specify the applicable dimensional class and revision; nominal size alone does not define every tolerance.
View shared nominal sizes ↗DIN 3771
For a legacy DIN drawing, confirm dimensions and the applicable DIN ISO 3601 requirements before substitution.
Open engineering reference ↗British size references
Record the exact BS reference and dimensions. For a BS 1516 enquiry, include the original chart or drawing for verification. BS 1806 and BS 4518 references should not be substituted by name alone.
Open engineering reference ↗Metric and legacy references
For a metric ring, supply ID × CS and drawing tolerances. For BS or DIN references, provide the original size designation and drawing. Do not assume that a similar metric dimension is an interchangeable standard size.
