Studs & Nuts, M6 (3" Lathe Chucks)

Studs & Nuts, M6 (3" Lathe Chucks) - Main image
$2.53 $3.95 In stock

These hardened studs & nuts are used to mount chucks and adapters on the mini lathe spindle. Because they are hardened they will last a lot longer than the ones that come on the mini lathe.

4 M6 x 30 studs and 4 M6 nuts.


These are the studs and nuts you need to mount a 3" 4-jaw chuck on the mini lathe. Use them to mount your shop-made faceplates and larger chuck adapters, too.

Customer Reviews (4.6 / 5 · 5 reviews)

Edward O. ★★★★★

The threads are cut clean and the hardened steel really holds up—no galling after a dozen chuck swaps on my lathe. These are an easy upgrade over the softer stock bolts.

Richard ★★★★★

I use these for swapping chucks on my mini lathe, and the hardened threads are holding up way better than the originals after dozens of changes. They seat snugly without binding, which was my main gripe before.

Abigail ★★★★★

The hardened steel really makes a difference—the stock studs on my lathe stripped within a month, so this set feels like a proper upgrade. Threads meshed cleanly with my M6 chuck, no wobble or binding. Honestly, worth the few extra bucks to not deal with that headache again.
