About the Mahr Precision Steel Gauge Block Set
Mahr has manufactured precision hand tools and gauges for well over a century, and its steel gauge block sets follow the same rigorous manufacturing discipline as its better-known form and surface measurement instruments. Sets are available across multiple grades to suit shop-floor and laboratory needs.
A natural fit for facilities that already run Mahr form testers or hand tools and want a matching reference standard from the same manufacturer.
