I’ve had this Dewalt DW744 table saw for about 10 years. It’s a cornerstone of my woodworking. Recently went to change blades and the arbor nut was stripped out. Dewalt says they no longer support this saw either. Unfortunately, I haven’t been able to find a replacement in the USA or the UK. A 5/8” nut shouldn’t be that difficult to find but I have no idea what the thread count is. Any ideas would be appreciated. The Dewalt part #153439-00.
