Starrett Inside Micrometers

Starrett Solid-Rod Inside Micrometers

No. 124 Series Sets (2 - 12")
No. 124M Series Sets (50 - 300 mm)

These Starrett Inside Micrometer are the most popular inside micrometers because of their lightness, ease of use and range. They are very useful for measuring inside diameters of cylinders and rings, measuring parallel surfaces, etc.

The desired range is obtained by assembling rods and spacing gages to the micrometer head. Measuring rods are provided with a shoulder that is set accurately in the micrometer head and lock in position. When assembling rods to the A and B heads, the reading line on the micrometer head should be lined up with the marking on each rod (except for the 2 - 3" and the 50 - 75 mm rods).

Rod diameters are approximately 1/4" (6 mm) on the A and B sizes. Each rod has individual length adjustment for the anvil by means of special wrenches furnished.
