Spi 15-080-5 Rectangle Steel Gage Block 0.7 in Grade AS-1

Product Description

The SPI 15-080-5 is a rectangular steel gage block measuring 0.7 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 on the shop floor or in the metrology lab. This block ships with NIST certification, confirming traceability to national measurement standards. Grade AS-1 indicates a high-accuracy tolerance class suitable for calibration and inspection work. The steel construction delivers the durability and stability required for repeated use in production and quality-control environments.

Rectangular gage blocks at this size are commonly used in dimensional inspection, machine setup, and instrument calibration across manufacturing, tooling, and metrology applications. They are appropriate for use in quality labs, tool cribs, and production floor inspection stations. Licensed metrology technicians, machinists, and quality engineers typically handle calibration-grade blocks. The included NIST certification makes this block suitable for applications requiring documented measurement traceability in regulated or audited environments.

Key Features

• Grade AS-1 accuracy for calibration and precision inspection use
• Rectangular steel construction provides durability and dimensional stability
• NIST certification included for traceable measurement documentation
• 0.7-inch nominal size expressed to five decimal places (0.70000 inches)
• Single-block packaging supports individual instrument calibration setups

Compatibility

Designed as an OEM-style replacement or supplemental block for use with standard rectangular gage block sets and comparator setups requiring a 0.7-inch reference standard.

Installation Notes

Gage blocks should be handled by qualified metrology or inspection personnel following established metrology practices. Blocks must be wrung together using proper technique on a clean, stable surface to prevent measurement error or surface damage. Store in the provided case away from temperature extremes and moisture to maintain dimensional stability and surface integrity. Do not use gage blocks as mechanical stops or clamps, as this will damage the precision-ground surfaces.
