Studs & Nuts, M8
4 M8 x 1.25mm studs and 4 M8 nuts.
These are the studs and nuts you need to mount a chuck on the HiTorque 7x16 mini lathe with a 4" (100 mm) flange. Use them to mount your shop-made faceplates and larger chuck adapters, too.
The nuts are hardened so they won't wear out from repeated use.
