Mitutoyo 611176-531 Steel Gage Block 0.136 in Grade 0

Product Description

The MITUTOYO 611176-531 is a rectangular steel gage block measuring 0.136 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify dimensional accuracy, and set up comparators and fixtures. Grade 0 represents a high level of dimensional accuracy, making this block appropriate for calibration lab use and demanding shop-floor inspection tasks. Each block ships with a Certificate of Inspection confirming it meets ASME standards. The steel construction provides durability and resistance to wear over repeated use in metrology applications.

This gage block is suited for use in tool rooms, metrology labs, quality control departments, and precision manufacturing environments. It serves as a reference standard when calibrating micrometers, calipers, height gages, and comparators. Machinists, metrologists, and quality technicians working in both light manufacturing and heavy industrial settings rely on Grade 0 blocks when traceable dimensional verification is required. The single-block configuration is useful for targeted calibration needs or as a replacement in an existing gage block set.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction for long-term durability and wear resistance
• 0.136-inch nominal size with five-decimal inch precision
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block accessories, holders, and wringing fixtures used in ASME-compliant metrology setups.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control professionals. Blocks should be stored in a clean, dry environment at a stable temperature to prevent thermal expansion errors. Before use, clean contact surfaces with an appropriate solvent and lint-free cloth to remove oils and debris that could affect accuracy. Never use gage blocks on surfaces that may cause impact or abrasion damage to the precision-ground faces.
