Mitutoyo 614158-531 Square Steel Gage Block 0.118 in Grade 0

Product Description

The MITUTOYO 614158-531 is a square steel gage block measuring 0.118 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in the metrology lab. This block is made from steel and ships with a Certificate of Inspection, confirming it meets ASME Grade 0 tolerances. Grade 0 is a high-accuracy grade suitable for demanding measurement and calibration work. Dimensional metrology technicians, quality control inspectors, and tool room machinists are the primary users of this type of standard.

This gage block is used in precision measurement applications where a traceable, certified reference dimension is required. Typical scenarios include setting dial indicators and electronic gauges, calibrating micrometers and calipers, and establishing reference datums for inspection fixtures. The 0.118-inch size fills a specific step in a gage block set and is appropriate for both production inspection and laboratory metrology environments at the Grade 0 level.

Key Features

• Grade 0 accuracy per ASME standards, providing tight dimensional tolerances for calibration and inspection use
• Steel construction for durability and dimensional stability under normal shop and lab conditions
• 0.118-inch nominal size for precise reference measurement at that dimension
• Includes Certificate of Inspection for traceability documentation
• Square block form factor for stable surface contact during wringing and gauge setup

Compatibility

Designed as an OEM-style precision reference standard compatible with general gage block accessory sets and holders designed for square-style gage blocks conforming to ASME standards.

Installation Notes

Gage blocks are handled and used by metrology technicians and quality control professionals. Always clean block surfaces with an appropriate solvent and lint-free cloth before use to prevent contamination that could affect accuracy. Store the block in its case when not in use to protect lapped surfaces from corrosion and mechanical damage. Do not drop or stack blocks on hard surfaces, as edge damage will compromise dimensional integrity.
