Description
The MITUTOYO 611310-531 is a rectangular steel gage block ground to a nominal length of 0.01 inches and certified to Grade 0 accuracy per ASME standards. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, verify inspection fixtures, and set comparators to a known length. This block is manufactured from steel, delivering the hardness and dimensional stability required for repeated use in metrology labs, quality-control departments, and tool rooms. Grade 0 indicates a tighter tolerance class suitable for calibration-room and reference applications where measurement uncertainty must be minimized.
This gage block is intended for use by metrologists, quality technicians, and precision machinists who need a reliable length reference at the 0.01-inch nominal size. It is suited for individual use as a single-block reference or as part of a wrung stack to build up a target dimension. Typical applications include setting dial indicators, bore gages, and height gages, as well as verifying the accuracy of micrometers and calipers in light manufacturing and inspection environments.
Key Features
- Grade 0 accuracy class per ASME standards for tight-tolerance reference work
- Rectangular steel construction provides hardness and long-term dimensional stability
- 0.01-inch nominal length suitable for stacking or standalone reference use
- Lapped and wrung-compatible faces allow precise block-to-block adhesion without fasteners
- Packaged individually for single-block purchase or replacement of a set component
Compatibility
Designed as an OEM-style individual gage block conforming to ASME standards, compatible with standard rectangular gage block sets and accessories that accept blocks at the 0.01-inch nominal size.
Installation Notes
Gage blocks should be handled by a qualified metrologist or calibration technician following established metrology procedures. Allow blocks to thermally stabilize to 68 degrees F (20 degrees C) before use, as steel expands and contracts with temperature changes that can affect measurement accuracy at this tolerance class. Clean mating faces with an approved gage-block cleaning solution before wringing; never use abrasive materials on the lapped surfaces. Store blocks in their protective case when not in use to prevent corrosion and surface damage.
