The Starrett No. 207Z Stainless Steel Seam Micrometer is a precision measuring tool from Starrett, part of the company’s Commander line, built with a narrow, blade-style anvil that reaches into seams, grooves, and recesses a standard flat-anvil micrometer can’t measure. Gunsmiths and machinists use a seam micrometer to check wall thickness and depth in spots a conventional micrometer simply won’t fit into. Its stainless steel construction resists the corrosion a carbon-steel tool would pick up from regular handling and oil exposure on the bench.
