Spi 11-348-0 Gage Block Set 10 Pc Steel Nist

Product Description

The SPI 11-348-0 is a 10-piece steel gage block set designed for precision measurement and calibration tasks in metrology, machining, and quality control environments. Each block is individually serialized and manufactured to Accuracy Grade 0, with tolerances ranging from 0.000016 to 0.000044 inches, making this set suitable for high-precision verification work. The set includes 9 individual gage blocks plus a wring or reference piece. A NIST certification is included, providing traceability for documented calibration requirements. This set is typically selected by machinists, quality technicians, and calibration specialists who need reliable reference standards for surface plate work, comparator setups, and tool verification.

This gage block set is suited for use in precision machine shops, tool rooms, inspection departments, and calibration labs handling both production and reference-grade measurement tasks. The Grade 0 accuracy classification makes it appropriate for inspection-level work where tight tolerances must be verified against a traceable standard. The rectangular steel blocks are compatible with standard wringing techniques used in comparative measurement setups.

Compatibility

Designed as a general-purpose Grade 0 steel gage block set suitable for use with standard surface plates, sine bars, comparators, and other precision metrology equipment that accepts rectangular gage block references.

Installation Notes

Gage blocks are handled and set up by metrology technicians, machinists, or quality inspectors working in controlled measurement environments. Blocks should be stored in their case when not in use and kept free of moisture, oils, and debris that can affect wringing surfaces. Always allow blocks to thermally stabilize at ambient shop temperature before use to prevent measurement error. Follow established wringing procedures and avoid sliding blocks on abrasive surfaces to preserve flatness and surface finish.
