Mitutoyo 614116-531 Square Steel Gage Block 0.16 in Grade 0

Product Description

The MITUTOYO 614116-531 is a square steel gage block ground and lapped to Grade 0 accuracy, measuring 0.16 inches in length. Gage blocks are precision length standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machining and inspection environments. This block ships with a Certificate of Inspection confirming it meets ASME standards. Grade 0 tolerance is a tight accuracy class suited for calibration labs and high-precision inspection work. Machinist, metrologist, and quality control technician are the typical users who reach for a block at this accuracy level.

This gage block is appropriate for dimensional inspection, tool room calibration, and metrology lab applications where a traceable, certified length reference is required. At 0.16 inches, it serves as a single-size reference standard and can be wrung with other blocks in a set to build up composite measurements. It is suited for both industrial production environments and calibration laboratory use where ASME-compliant length standards are required.

Key Features

• Grade 0 accuracy class per ASME standards for tight-tolerance calibration and inspection work
• Steel construction provides durability and stability across typical shop and lab temperature ranges
• 0.16 inch nominal size for use as a standalone reference or as part of a wrung stack
• Includes Certificate of Inspection for traceability documentation
• Square form factor for consistent wringing and stable surface contact

Compatibility

Designed as an OEM-style precision length standard compatible with standard gage block accessories, holders, and comparator setups requiring ASME-compliant Grade 0 steel blocks.

Installation Notes

Gage blocks are handled and used by machinists, metrologists, and quality control technicians. Before use, clean mating surfaces with a lint-free cloth and appropriate solvent to remove oils and debris. When wringing blocks together, slide and press gently to form a molecular bond without abrasion. Store in a protective case away from humidity and temperature extremes to prevent corrosion and dimensional drift.
