Starrett 92844 Steel Gage Block Set Grade 0 81 Piece

Product Description

The STARRETT 92844 is an 81-piece steel gage block set rated to Grade 0 accuracy, covering a measurement range of 0.05 to 4 inches. These blocks are used to establish precise reference dimensions for calibration, inspection, and layout work in precision measurement environments. The set conforms to ASME B89.1.9-2002 and includes NIST NVLAP traceable certification documentation, making it suitable for shops and labs where documented traceability is required. Machinists, calibration technicians, and quality control professionals use sets like this to verify measuring instruments and set up precision tooling.

This set is appropriate for tool rooms, metrology labs, machine shops, and manufacturing quality departments. The 81-piece configuration provides a wide range of combinable dimensions across four step increment groups, allowing users to build virtually any target dimension within the covered range. It is well suited for both bench-level inspection work and formal calibration procedures where Grade 0 accuracy is specified.

Installation Notes

Gage blocks should be handled by calibration technicians or trained metrology personnel. Before use, blocks should be wrung together on a clean, flat surface free of debris or burrs. Store blocks in the provided case and keep them away from temperature extremes to maintain dimensional accuracy. Follow shop or lab calibration interval procedures to maintain traceability documentation.
