Starrett 92872 Gage Block Set 88 Pc Steel

Product Description

The STARRETT 92872 is an 88-piece steel gage block set built to ASME B89.1.9-2002 dimensional accuracy standards. Gage blocks are precision-ground reference standards used to calibrate measurement instruments, set up machine tools, and verify part dimensions to tight tolerances. This set is Grade 0, placing it at a high level of dimensional accuracy suited for quality control labs, toolrooms, and production floor calibration work. A NIST and NVLAP traceability certification is included, which is required documentation for ISO and other quality management system audits. Machinists, metrologists, and quality technicians are the primary users of this set.

This set is appropriate for applications in manufacturing, tool and die, metrology labs, and precision machining environments where traceable dimensional reference standards are required. Grade 0 blocks are commonly used as working standards for calibrating micrometers, calipers, height gauges, and comparators. The 88-piece count provides a wide range of stacked combinations to achieve virtually any target measurement within the set range. The included NIST and NVLAP traceability certification supports compliance with ISO 9001, AS9100, and similar quality management programs.

Key Features

• 88-piece steel rectangular block set covering a broad range of stacked measurement combinations
• NIST and NVLAP traceability certification included for quality system compliance documentation
• Steel construction provides durability and dimensional stability for long-term toolroom use
• Certification included with the set, ready for immediate use in calibrated environments

Compatibility

Designed as a Grade 0 working standard compatible with standard gage block accessories including holders, jaws, and scribers that conform to ASME B89.1.9-2002 block dimensions.

Installation Notes

Gage blocks should be handled by a qualified metrologist or trained quality technician. Store blocks in their fitted case away from moisture, heat sources, and contaminants to prevent corrosion and dimensional changes. When wringing blocks together, ensure surfaces are clean and lightly oiled to avoid galling the precision-ground faces. Refer to ASME B89.1.9-2002 and your facility calibration procedures for proper handling, storage, and recalibration intervals.
