Description Condition Used This gauge block set is in “Used” condition. Product Overview The Mitutoyo 516-980 is a specialised Micrometer Inspection Gauge Block Set (Grade 2). Unlike standard gauge block sets that are designed to build up any dimension, this kit is specifically curated to verify the accuracy of micrometers (typically 0-25mm) and check for specific errors in the spindle screw. The set typically includes blocks in specific steps (such as 2.5mm, 5.0mm, 10.0mm, 15.0mm, 20.0mm, 25.0mm). These intervals are chosen not just to check the overall length, but to test the micrometer at different rotational positions of the thimble (e.g., 0°, 90°, 180°, 270°). This allows you to detect “Periodic Error” (drunken thread) in the micrometer spindle—something a single 25mm standard cannot do. Grade 2 (Workshop Grade): These blocks are manufactured to Grade 2 tolerance. This is the standard “Workshop Grade” intended for mounting on jigs, setting tools, and verifying the accuracy of mechanical instruments on the shop floor. Brand Information Mitutoyo Corporation (est. 1934) is the global benchmark for dimensional metrology. Their gauge blocks are the reference standard for the entire industry, known for their exceptional surface finish, wringing properties, and long-term dimensional stability.
