Mitutoyo 611135-541 Steel Gage Block 0.10005 in Grade AS-1

Product Description

The MITUTOYO 611135-541 is a rectangular steel gage block ground to a nominal length of 0.10005 inches and certified to ASME Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in a metrology lab. This block ships with a Certificate of Inspection confirming it meets the stated tolerance grade. Grade AS-1 is a working-grade standard suitable for demanding inspection and quality-control applications. Machinists, toolroom technicians, and metrology professionals are the typical end users.

This gage block is suited for dimensional inspection in precision manufacturing environments, including toolrooms, quality labs, and production floors. It serves as a reference master for setting height gauges, bore gauges, snap gauges, and similar instruments. The 0.10005-inch size fills a specific incremental step in a gage block set build-up, making it a practical individual replacement or supplement block when a single size is needed without purchasing a full set.

Key Features

• Ground to 0.10005 inches nominal length for precise dimensional reference
• Grade AS-1 accuracy per ASME standards, suitable for production inspection work
• Steel construction provides durability and long-term dimensional stability
• Includes Certificate of Inspection for traceability documentation
• Single-block packaging supports targeted replacement without full-set purchase

Compatibility

Designed as a working-grade rectangular gage block compatible with standard ASME gage block sets and accessories including block holders, jaw sets, and scribing accessories that accept rectangular-style blocks.

Installation Notes

Gage blocks should be handled by metrology technicians or toolroom personnel trained in proper wringing technique to prevent burrs and surface damage. Store blocks in a clean, dry environment and allow them to thermally stabilize to ambient temperature before use to avoid measurement error from thermal expansion. Clean mating surfaces with an approved gage block cleaner before wringing. Never drop or stack blocks loosely, as surface damage will compromise accuracy.
