Mitutoyo 516-935-26 Steel Gage Block Set Grade AS-1 9 Piece

Product Description

The MITUTOYO 516-935-26 is a 9-piece rectangular steel gage block set manufactured to Grade AS-1 accuracy per ASME B89.1.9-2002. Gage blocks are precision reference standards used to calibrate measuring instruments and verify dimensional accuracy in manufacturing, inspection, and metrology environments. This set covers a range of 1/16 inch to 2 inches and is individually serialized for traceability. A NIST Traceability Certification is included with the set, making it suitable for quality control labs and tool rooms where documented calibration standards are required.

This set is suited for dimensional inspection work in manufacturing facilities, machine shops, and calibration laboratories. It supports applications where precise length references are needed to calibrate micrometers, calipers, comparators, and surface plates. The included certification supports audit-ready inspection programs. Metrology technicians, quality engineers, and precision machinists are the primary users of this type of gage block set.

Installation Notes

Gage blocks are precision instruments and should be handled by trained metrology or quality control personnel. Store blocks in the provided case and keep them away from contamination, corrosion, and temperature extremes that could affect dimensional stability. Clean blocks and wringing surfaces before use following standard metrology practices. Do not drop or stack blocks without proper wringing technique, as surface damage will affect accuracy.
