Excellent construction, very handy for mounting a lug bag gauge to a base
It's difficult to tell, but the piece looks like it's in a natural finish in Amazon's picture. The one I received appears to be black anodized. Overall, it's perfect for mounting a lug back gauge onto a magnetic base or fixture. Typical quality from Starrett (if we're only talking about their products still made in the USA).

Great product for dial indicators
I use mine as an adapter to put my digital indicator on my support arm while taking critical measurements on aircraft.

Excellent quality, typical Starrett
Excellent quality, typical Starrett. However, the 1/4" stem did not fit my 8mm Noga mag base clamp. I made a split collet out of an 8mm bolt by drilling the bolt out 1/4", cutting it down to about 10mm long, and splitting it along the side with a slitting saw. Now I can use this with my lug backed Mitutoyo indicator and Noga mag base.

Attachment.
Good quality product. It will certainly serve the purpose. I would recommend this to anyone but please the size you need.

As described
The item I received is definitely black even though the picture shows it as natural steel color. Works perfectly and seems extremely durable

Can be used with Noga stand if used with PT00764 bushing
If you have a Noga indicator stand, and want to attach it to the lug at the back of a dial indicator, use this along with Starrett PT00764 split bushing. The bushing adapts the 1/4" outside diameter of the 657Y post to the 3/8" inside diameter hole of the Noga holder. Note if your dial indicator already has a 3/8" stem, then it can be attached directly to the Noga holder without any additional attachments.
