Mitutoyo 611219-531 Steel Gage Block 0.95 in Grade 0

Product Description

The MITUTOYO 611219-531 is a rectangular steel gage block measuring 0.95 inches in overall length, manufactured to Grade 0 accuracy standards. Gage blocks serve as precision length references used for calibrating measuring instruments, setting comparators, and verifying dimensional tolerances on the shop floor or in a metrology lab. The Grade 0 designation indicates a high level of dimensional accuracy and flatness conforming to ASME standards. Each block ships with a Certificate of Inspection documenting its measured deviation, making it suitable for quality-controlled environments where traceability is required.

This gage block is intended for use in precision measurement applications across manufacturing, toolroom, and inspection environments. It functions as a reference standard when calibrating micrometers, calipers, height gages, and similar instruments. Machinists, quality technicians, and metrologists typically use Grade 0 blocks where tighter tolerance verification is needed compared to general working-grade blocks. The 0.95-inch size fills a specific incremental step in a gage block set or can be used individually as a standalone reference length.

Key Features

• Grade 0 accuracy conforming to ASME standards for high-precision measurement applications
• Steel construction provides durability and dimensional stability under typical shop and lab conditions
• 0.95-inch nominal length with a five-decimal-place dimensional reference for precise calibration work
• Includes Certificate of Inspection for traceability documentation in quality-controlled environments
• Single-block packaging allows individual procurement without purchasing a full set

Compatibility

Designed as a standalone Grade 0 rectangular steel gage block suitable for use with standard gage block accessories and holders conforming to ASME B89.1.9 specifications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality lab personnel. Before use, clean the measuring faces with a lint-free cloth and an appropriate solvent to remove oils and debris that can affect wringing and accuracy. Store blocks in their case away from temperature extremes, as thermal expansion can affect readings. Do not drop or stack blocks unprotected, as surface damage to the lapped faces will compromise accuracy.
