Mitutoyo 611157-541 Steel Gage Block 0.117 in Grade AS-1

Product Description

The MITUTOYO 611157-541 is a rectangular steel gage block with a nominal size of 0.117 inches and an accuracy grade of AS-1. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in a calibration lab. This block conforms to ASME standards and ships with a Certificate of Inspection, documenting that the block has been measured and meets the stated accuracy grade. AS-1 is a working-grade classification suited to general inspection and measurement tasks in a production or toolroom environment.

This gage block is used wherever a reliable, traceable dimensional reference is needed. Typical applications include setting dial indicators, height gages, and snap gages, as well as verifying fixture dimensions and checking machined part tolerances. It is well suited to machine shops, quality control departments, calibration labs, and toolrooms. Metrology technicians, quality engineers, and precision machinists are the primary users. The block is sold individually and is compatible with standard gage block accessory sets for stacking.

Compatibility

Designed as an OEM-style rectangular gage block for use with standard gage block sets and accessories in toolroom, inspection, and calibration applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality personnel. Before use, clean all mating surfaces with an appropriate gage block cleaning solution to remove oils, debris, and oxidation. When wringing blocks together, apply light pressure and a sliding motion to achieve full surface contact. Store the block in its case away from temperature extremes and corrosive environments to preserve surface finish and calibration integrity.
