The Starrett 569 Case Neck Micrometer is one of the best micrometers on the market today and is the perfect tool to measure case neck thickness to get a precise measurement. The rigid steel “half” frame combined with an anvil diameter of 0.185″ and 0.001″ graduations help to ensure accurate, repeatable measurements. This micrometer comes shipped in a fitted case to keep the tool functioning for a lifetime.
