I'd talk check it again, and either talk to them about it, or return it. M40-1.5 is the standard for ER32 chucks. At least according to the Rego-fix documentation I have. See attached.?
It's also what LMS carry as a spare part.

Hello, All, I have several ER-32 collet chucks of different types; one for my mini-lathe, one for an R8 spindle to match my mini-mill, and a 2MT for my rotary table. These all use the same M40-1.5 collet nut, which is basically available everywhere. I recently purchased and received an ER-32 Spin Indexer from Little Machine Shop, for use on my mill. To my surprise, I noticed that the collet nut threads are M40- 1.0, not M40-1.5. I spent a little time searching the internet and could not find an ER-32 M40-1.0 collet nut. My concern is where I will obtain replacement nuts if and when this becomes necessary. I will email LMS and ask if they carry these collet nuts, but am concerned that I may be out of luck in the future. Does anyone know if M40-1.0 is used routinely on ER-32 collet chucks? Thanks to everyone for their help! -- Regards, Charlie New Jersey, USA
