    Discussion of Fastener Sizes and Scale Equivalents, and this thread can be updated as required.

    Whitworth Fastener Dimensions​

    Set out below are tables of Whitworth fastener dimensions for full size and Gauge O, Gauge 1 Gauge 3 scale equivalents. The scale equivalents are given in millimetres and inches. Please note that the washer dimensions (shown in italics) are estimates as no relevant standard was available at the time of making up the tables. If someone has the standards for washer sizes could you kindly let us have details in the discussion thread. Following these tables are downloadable excel *.xls files for each of the scales which have both the metric and imperial dimensions as well as the full size dimensions included.
