Mitutoyo 611117-531 Steel Gage Block 0.17 in Grade 0

Product Description

The MITUTOYO 611117-531 is a rectangular steel gage block measuring 0.17 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks serve as primary length reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in precision machining and inspection environments. Grade 0 represents a high level of dimensional accuracy, making this block appropriate for tool room and quality-assurance applications. A Certificate of Inspection is included with each unit, confirming the block meets stated accuracy requirements at the time of manufacture. Machinists, metrologists, and quality technicians working in production or calibration labs are the primary users.

This gage block is suited for dimensional inspection work in machine shops, tool rooms, and calibration laboratories. It functions as a length reference for setting dial indicators, height gages, and comparators. Its steel construction provides durability and resistance to wear under repeated handling. The 0.17-inch size fills a common incremental position in a gage block set build-up or serves as a standalone reference for specific dimensional setups requiring that nominal value.

Key Features

• Grade 0 accuracy per ASME standards for high-precision reference use
• 0.17-inch nominal length for incremental stack builds or dedicated setups
• Steel construction for durability and long service life
• Certificate of Inspection included with each unit
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style rectangular gage block compatible with standard gage block sets and accessories conforming to ASME specifications for length reference standards.

Installation Notes

Gage blocks are precision instruments handled by metrology technicians and quality inspectors. Always clean contact surfaces with an appropriate gage block cleaning solvent before wringing or stacking. Store blocks in their original case away from heat, humidity, and magnetic fields. Do not use damaged or corroded blocks as reference standards, as surface defects directly affect measurement accuracy.
