固定式跟刀架與移動式跟刀架固定座，M8

The M8 threading fits perfectly on my steady rest, and the 28 mm length gives just enough grip without sticking out awkwardly. It’s a small part, but the machining is clean and it holds the fingers firmly in place.

The M8 threading matched the steady rest on my mini lathe perfectly, and the 28 mm length was exactly right for the fingers. These retainers feel solid when tightened, just what you need for a snug fit on the follower rest.

Took a chance on this retainer for my steady rest, and the M8 threading engaged smoothly without any wobble. The 28mm length worked as expected, but I wish the M5 threaded hole had a bit more depth for secure finger placement.
