Mitutoyo 614145-531 Steel Gage Block 0.105 in Grade 0

Product Description

The MITUTOYO 614145-531 is a square steel gage block measuring 0.105 inches in length, manufactured to Accuracy Grade 0 tolerances per ASME standards. Gage blocks of this type serve as dimensional reference standards used to calibrate measuring instruments, verify part tolerances, and set up precision measurement equipment. Grade 0 represents a high level of dimensional accuracy, making this block appropriate for calibration lab environments and tool room applications where tight measurement traceability is required. Each unit ships with a Certificate of Inspection to support quality documentation and calibration records.

This gage block is suited for use in machine shops, calibration labs, manufacturing facilities, and tool rooms where precision dimensional verification is performed. Technicians and metrologists use blocks like this to establish reference dimensions, stack combinations to reach target measurements, and validate the accuracy of micrometers, calipers, and comparators. The square geometry allows stable surface contact in both individual and stacked configurations.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• 0.105-inch nominal length in a square block form factor
• Steel construction for durability and wear resistance in repeated-use applications
• Certificate of Inspection included to support calibration documentation and traceability
• Single-piece packaging suitable for individual tool room or lab inventory

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessories including holders, jaws, and wringing fixtures intended for square-style gage blocks.

Installation Notes

Gage blocks are handled and used by machinists, metrologists, and quality technicians rather than installed in a traditional sense. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Clean block surfaces with a lint-free cloth before wringing or use to ensure accurate contact. Avoid dropping or stacking blocks on hard surfaces, as surface damage will compromise measurement accuracy.
