Spi 11-345-6 Gage Block Set 9 Pc AS-1 Steel

Product Description

The SPI 11-345-6 is a 9-piece steel gage block set covering a measurement range of 0.0625 to 2 inches. Each block is manufactured to AS-1 accuracy grade with a tolerance of 0.000016 inches, making this set suitable for precision measurement, calibration, and quality control work. The blocks are individually serialized and come with NIST-traceable certification, supporting traceability requirements in inspection environments. Machinists, metrologists, and quality technicians use sets like this for setting comparators, checking gauges, and verifying part dimensions on the shop floor or in the inspection lab.

This set is designed for precision measurement applications in machine shops, tool rooms, and quality control departments. It is appropriate for both production floor use and metrology lab environments where AS-1 grade accuracy is required. The steel construction provides durability under regular use conditions. The included NIST-traceable certification and individual block serialization make this set suitable for facilities that maintain documented calibration records and traceability chains.

Key Features

• AS-1 accuracy grade with 0.000016 inch tolerance per block
• Measurement range of 0.0625 to 2 inches across 9 blocks
• Steel rectangular block construction for durability and wringability
• Individually serialized blocks for traceability and documentation
• NIST-traceable certification included with the set

Compatibility

Designed as a general-purpose precision gage block set for use with standard comparators, surface plates, and inspection fixtures in machine shop and metrology applications.

Installation Notes

Gage blocks should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before wringing blocks together, inspect surfaces for burrs or contamination that could affect accuracy or damage lapped surfaces. Store blocks in the provided case and apply a light coat of appropriate corrosion-preventive oil when not in use for extended periods. Calibration intervals should be established according to your facility quality management procedures.
