    Hello, I am not sure what these are. All are stamped "left hand thread" ( which I believe is the coarse thread showing). On the left end is an 1/8" diameter spline shaft. The right ends have knurling parallel to the length of the tool. The nut on the left end unscrews, but has given me no clue. Turning the the small knurled piece on the right end in an arc ,turns the splined shaft in an arc ( does not rotate) . Overall length is approx. 7" They are also stamped 0-20, 0-50, 0-200 and 0-300. Thanks for any help, Lou

      They appear to be specialty go - no go tools that would be used by quality control to insure the item is within specs.

      Hello, fhrjr2. Thanks for the reply.I brought these in to work, still no definite answer. All of the small spline ends are the same diameter .108. The shafts that go through the body are different diameters, and offer a different level of resistance when you rotate the knob on the right end. Also noticed were the differences in the size of the end fittings , corresponding increase in diameter in relation to the ranges that are stamped on the body. The third photo in the original post shows the differences in the ends. If you look closely at the 4th photo, ( squinting may be required) you may see the difference in the shaft diameters.
