Your measuring tools are only trustworthy if you can check them against a known standard. Mahr gage block sets provide precision dimensional standards for calibrating, setting, and verifying precision measuring equipment. Available in steel, ceramic, and carbide configurations, these Mahr gage block sets cover a wide range of inspection and calibration requirements, from everyday shop-floor measurement to precision metrology and reference-standard applications.
Precision gage block sets for calibration and inspection
Manufactured to DIN EN ISO 3650, Mahr MarGage rectangular gage block sets provide stable, repeatable reference dimensions for verifying the accuracy of calipers, micrometers, comparators, gauges, and other dimensional measuring equipment. Select from 5-, 6-, 10-, 11-, 32-, 46-, 47-, 81-, 87-, 111-, and 121-piece configurations, with multiple tolerance classes and material options.
Mahr MarGage Steel Gage Blocks
Steel sets are a practical choice for inspection departments, machine shops and general dimensional verification, in multiple set sizes and ISO 3650 tolerance classes. Current CRB Supply steel configurations include MarGage 402 (32-pc), 404 (46-pc), 406 (87-pc), 408 (111-pc), 409 (121-pc), 411 (5-pc), 415 (6-pc) in Grades 0/1/2, plus an 81-piece rectangular steel set in Grade 0.
Ceramic Gage Block Sets for Metrology
Ceramic gage blocks resist corrosion, wear and scratching for long-term dimensional stability, and suit metrology rooms and demanding workshops alike. Available configurations include MarGage 402 C (32-pc), 404 C (46-pc), 405 C (47-pc), 406 C (87-pc), 408 C (111-pc), 409 C (121-pc) and 419 C (10-pc). Ceramic has a coefficient of thermal expansion similar to steel.
Gage Block Tolerance Classes
-
Grade 0: higher-accuracy inspection and reference applications
-
Grade 1: precision setting, inspection and calibration
-
Grade 2: general workshop and production use
Carbide Calibration Gage Block Set
CRB Supply also offers the 11-piece Mahr carbide calibration gage block set. Carbide provides extremely high wear resistance for reference and calibration work where long-term stability is a priority.
