Product Description

The Starrett 124AZ Solid-Rod Inside Micrometer Set is a versatile set of micrometers used for measuring inside diameters of cylinders and rings, measuring parallel surfaces, etc.

Obtain your desired range by assembling the rods and spacing collars to the micrometer head. When assembling rods to the A and B heads, line up the reading line on the micrometer head with the marking on each rod (except for the 2-3″ and 50-75mm rods). Rod diameters are approximately 1/4″ (6mm) on the A and B sizes, and approximately 11/32″ (8.5mm) on the C size. Each rod has individual length adjustment for the anvil using special wrenches furnished.

The 124AZ set includes six measuring rods and one spacing collar in a padded case.
