Starrett 657Y Indicator Attachment Magnetic Review

Excellent quality typical of Starrett. However, the 1/4" stem didn't fit my 8mm Noga magazine clip. I made a split collet out of an 8mm bolt by drilling a 1/4" bolt, tightening it to about a 10 mm length shortened and split it lengthwise Longitudinal cut side Now I can use this with my Mitutoyo bar and Noga magazine base display.

It's hard to say but in the picture from Revane the product looks like it has a natural finish. The one I received appears to be black anodized. Overall, it's ideal for attaching a backgauge to a magnetic base or mount. Typical Starrett quality (if we only talk about their products which are still made in the USA).

If you have a Noga indicator stand and want to attach it to the tab on the back of the indicator, use it with the Starrett PT00764 Split Sleeve. The sleeve adapts the 1/4" OD of the 657Y stand to the 3/8" ID hole of the noga holder. Note that if your dial indicator already has a 3/8" shank, it can be fitted directly to the Noga bracket without additional fasteners.
