The SPI 15-069-8 is a rectangular steel gage block measuring 0.2 inches, manufactured to Grade AS-1 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy in machining and inspection environments. This block includes NIST certification, confirming it has been measured and documented against national standards. It is a single-piece block intended for use in tool rooms, quality labs, and production floor inspection stations where traceable dimensional references are required.
This gage block is suited for metrology and dimensional inspection applications in manufacturing, machining, and calibration environments. Grade AS-1 represents a high-accuracy classification appropriate for laboratory and inspection-grade work. The block is used by quality technicians, tool and die makers, and precision machinists who need a reliable, certified reference standard for instrument calibration or part verification setups.
Designed as an OEM-style replacement or supplemental block for standard rectangular gage block sets used in precision metrology and dimensional inspection applications.
Gage blocks are handled and stored by metrology technicians and quality professionals, not field tradespeople. Before use, clean all mating surfaces with an appropriate solvent to remove oils or debris that could affect accuracy. Store the block in its case when not in use to prevent corrosion and surface damage. Do not drop or stack blocks without proper wringing technique, as surface damage will compromise accuracy and invalidate certification.
