Ferguson Nuts
Regular readers of this page will know the wrong bolts and nuts on a Ferguson tractor is something that really bugs me. Whilst restoring my Ferguson tractor I would rather try to cleanup and old 5/8" UNF nut than fit a new one. The reason for this, new 5/8" UNF nuts come with an Across Flats (A/F) distance of 15/16". 15/16" does not fit a Ferguson spanner. Ferguson used 1 1/16" A/F for it's 5/8" nuts. I have been searching for a 5/8" UNF nut with an A/F of 1 1/16" for many years.

I have secured a quantity of the 1 1/16" nuts and am offering them for sale.

I always have trouble with spanner sizes and thread sizes so I have also put together this sheet to keep handy in the garage. I've printed mine out and have it stuck on the wall in the garage next to the spanners.
