About the Mitutoyo 516-940-10
The 516-940-10 is part of Mitutoyo's long-running Series 516 rectangular gauge block range, supplied as a 47-piece set in Grade 0 — accurate enough for calibrating precision hand tools and setting comparators, while remaining more affordable than laboratory-grade 00 sets. Blocks are high-carbon, high-chrome steel, wrung together to build any required stacked dimension.
This is the set most calibration technicians reach for day-to-day: verifying micrometers and calipers during routine QC checks, setting dial/digital comparators to a known reference length, and general workshop-level dimensional verification.
