Value Collection 630-23906 Steel Gage Block 0.9 in Grade 0

Product Description

The VALUE COLLECTION 630-23906 is a Grade 0 rectangular steel gage block measuring 0.9 inches, used for precision dimensional measurement and calibration work. Gage blocks at this accuracy grade serve as transfer standards in metrology labs, machine shops, and quality control environments where tight tolerances must be verified. This block ships with NIST certification, confirming traceable dimensional accuracy to national standards. Machinists, toolmakers, metrologists, and quality technicians rely on Grade 0 gage blocks for instrument calibration, setup verification, and surface plate work.

This gage block is suited for use in precision manufacturing, tool and die, aerospace component inspection, and general metrology applications where a calibrated reference standard is required. Its rectangular form and steel construction make it compatible with standard gage block accessories including holders, jaws, and wringing fixtures. The included NIST certification documentation makes it appropriate for use in regulated quality management environments.

Key Features

• Grade 0 accuracy for high-precision calibration and measurement applications
• Nominal size of 0.9 inches for dimensional reference work
• Steel construction provides durability and dimensional stability
• Includes NIST certification for traceable accuracy to national standards
• Rectangular form compatible with standard wringing and stacking techniques

Compatibility

Designed as a standard rectangular gage block suitable for use with conventional gage block sets, holders, and accessories in metrology and precision machining environments.

Installation Notes

Gage blocks are handled and set up by machinists, metrologists, and quality technicians. Clean the block surfaces thoroughly before wringing or stacking to prevent surface damage and maintain accuracy. Store the block in its protective case when not in use to prevent corrosion and surface wear. Avoid contact with abrasive surfaces or tools that could alter the lapped faces.
