The SPI 15-013-6 is a rectangular steel gage block measuring 0.1008 inches, manufactured to Grade AS-1 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy in machining and inspection environments. This block includes NIST certification, confirming it has been measured and documented against national measurement standards. Grade AS-1 indicates a high level of dimensional accuracy suitable for calibration and inspection work. Machinists, quality control technicians, and metrologists use blocks like this as primary reference tools in tool rooms and inspection departments.
This gage block is suited for use in machine shops, manufacturing quality control labs, and precision inspection stations. It serves as a reference standard for setting dial indicators, height gages, and other precision measuring instruments. The rectangular form factor allows it to wring with other gage blocks in a set for building custom stack heights. It is appropriate for both production floor verification and laboratory calibration applications where traceable measurement standards are required.
Designed as an OEM-style replacement or supplemental block compatible with standard rectangular gage block sets and accessories used in precision metrology and dimensional inspection applications.
Gage blocks should be handled by metrology technicians or qualified machinists familiar with wringing techniques and proper storage practices. Clean block surfaces with an appropriate gage block cleaning solution before and after use to prevent corrosion and contamination. Store blocks in a protective case away from temperature extremes to maintain dimensional stability. Never drop or slide blocks across hard surfaces, as surface damage will compromise accuracy.
