Mitutoyo 611176-541 Steel Gage Block 0.136 Inches AS-1

Product Description

The MITUTOYO 611176-541 is a rectangular steel gage block manufactured to ASME AS-1 accuracy grade standards. Gage blocks serve as dimensional reference standards for calibrating measurement tools, setting comparators, and verifying part tolerances on the shop floor or in the metrology lab. This block measures 0.136 inches in overall length and is constructed from steel, providing the stability and hardness required for repeatable, high-precision measurement tasks. Each unit ships with a Certificate of Inspection documenting conformance to the stated accuracy grade. Calibration technicians, machinists, and quality control professionals rely on AS-1 grade blocks where close dimensional tolerances must be verified or transferred.

This gage block is suited for use in dimensional metrology applications across manufacturing, tool-and-die, and inspection environments. It functions as a standalone reference block or as part of a set when wringing multiple blocks to build a target dimension. Typical applications include machine tool setup, comparator calibration, and incoming or in-process quality inspection. The 0.136-inch nominal length fills a specific step in incremental block sets commonly used in precision layout and measurement workflows.

Key Features

• AS-1 accuracy grade per ASME standards for high-precision dimensional reference
• Rectangular steel construction for durability and long-term dimensional stability
• 0.136-inch nominal length for precise incremental measurement builds
• Includes Certificate of Inspection confirming conformance to accuracy grade
• Single-piece packaging suitable for replacement or set supplementation

Compatibility

Designed as an OEM-style rectangular gage block for use with standard wringing-compatible gage block sets in precision metrology and inspection applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control personnel, not installed in the traditional sense. Clean block surfaces thoroughly with an appropriate solvent and lint-free cloth before use to prevent contamination that could affect measurement accuracy. Store blocks in a controlled environment away from humidity and temperature extremes to maintain dimensional stability. Do not drop or slide blocks across abrasive surfaces, as damage to the lapped faces will compromise accuracy.
