Center Gage, 60 Degree, Starrett

Finally got around to checking some oddball British threads and the Whitworth 55° side saved the day — dead-on match every time. Nice having both metric and imperial options in one tool.

The scale for checking threads per inch has already saved me from having to dig out my thread pitch gauge several times. It’s a well-made, practical tool that does exactly what it should for the price.

The machined edges are crisp and the 60-degree markings line up perfectly against my lathe work. I used the thread-per-inch scale to check a worn bolt and it matched my pitch gauge exactly, so it's earning its spot in my toolbox.
