The Sinclair Case Neck Micrometer is built around a Starrett micrometer head capable of measuring in .0001inch increments.This tool is designed specifically for handloaders to accurately measure case neck wall thickness. The micrometer head and anvil are completely adjustable so the handloader can measure the neck wall thickness right up to the junction of the case neck and shoulder. These adjusting features, plus the ratchet control built into the micrometer head, allow the user to zero the tool to suit their own feel and their own needs.
The tool is mounted to a stainless steel base and allows the handloader to have both hands free to use when measuring brass. The micrometer head is mounted in an anodized aluminum frame, and the anvil is made of stainless steel. This micrometer will work for .17 caliber cases and larger. The tool comes pre-zeroed. MADE IN THE U.S.A.
