Mitutoyo 516-947-26 Gage Block Set 87 Pc AS-1 Steel

Product Description

The MITUTOYO 516-947-26 is an 87-piece rectangular steel gage block set manufactured to AS-1 accuracy grade and conforming to ASME B89.1.9-2002. Gage blocks are the primary reference standards used to verify, calibrate, and set measuring instruments across machining, inspection, and metrology environments. This set is individually serialized for traceability and ships with an inspection certificate, making it suitable for use in quality systems that require documented calibration records. The rectangular steel construction provides the dimensional stability and wringing capability expected from a professional-grade reference standard. Metrologists, calibration technicians, and precision machinists are the primary users.

This gage block set is appropriate for dimensional metrology labs, machine shops, and quality control departments in both manufacturing and industrial service environments. It supports applications such as setting comparators, qualifying surface plates, calibrating micrometers and calipers, and verifying fixture dimensions. The 87-piece count provides the combination range needed for a wide variety of buildup dimensions. The included wooden case keeps blocks organized, protected from surface damage, and ready for immediate use on the bench or in a controlled metrology environment.

• Rectangular steel construction for stable wringing and long service life
• Each block individually serialized for full traceability
• Inspection certificate included to support ISO and quality system documentation requirements
• Wooden storage case included for organized, protected storage

Compatibility

Designed as a general-purpose reference standard set compatible with standard gage block accessories including holders, jaws, and scribing points that accept rectangular-style blocks conforming to ASME B89.1.9-2002 geometry.

Installation Notes

Gage blocks are handled and used by calibration technicians and metrologists following established metrology procedures. Blocks should be cleaned and wrung together on a clean, vibration-free surface using proper wringing technique to avoid surface damage. Store blocks in the provided wooden case when not in use to prevent corrosion and surface wear. Do not use gage blocks as a substitute for hardened measuring anvils or under conditions that expose them to abrasive materials or corrosive environments.
