Starrett Complete Snug Assembly with Post Hole - 1/4 and 3/8 Holes - PT18724

Great Product. Just What The Doctor Ordered.

This was too small for my base post. Was not able to use it.

Excellent in every way, typical Starrett

Love it. Solid mount.

as advertised fast delivery

It wont fit any SPI or any other generic/Chinese made mag base

useful tool around mill and lathe

Its a little fiddly to use at first, where it seems you either over or under tighten it causing the indicator to droop easily or be impossible to move without shifting other things, but once you hit the sweet spot, its amazing.

Quality wise it is a good product. I am still waiting for another item so I could check how it fits with 3/8 round bars.
