Value Collection 630-33656 Steel Gage Block 0.65 in Grade AS-1

Product Description

The VALUE COLLECTION 630-33656 is a rectangular steel gage block measuring 0.65 inches, manufactured to Grade AS-1 accuracy standards. Gage blocks are precision length reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machining and inspection environments. This block includes NIST certification, providing a traceable measurement standard required in quality-controlled manufacturing and metrology labs. It is handled and installed by machinists, quality technicians, and metrologists who rely on certified reference standards for process control and instrument calibration.

This gage block is suited for use in tool rooms, inspection departments, and production environments where precise dimensional verification is required. At 0.65 inches, it serves as a direct reference standard for setups involving that specific dimension. NIST-certified blocks are commonly required in aerospace, automotive, and general manufacturing quality systems to satisfy calibration traceability requirements. Individual blocks can also be wrung together with other gage blocks to build up composite reference dimensions.

Key Features

• Grade AS-1 accuracy provides tight dimensional tolerances suitable for precision inspection and calibration work
• NIST certification included, establishing traceable measurement standards for quality system compliance
• Steel construction offers durability and stability for repeated use in tool room and production environments
• 0.65 inch nominal size available as a single-piece reference standard
• Rectangular form is compatible with standard gage block wring and stacking techniques

Compatibility

Designed as an OEM-style individual reference standard compatible with standard rectangular gage block sets and accessories used in general metrology and inspection applications.

Installation Notes

Gage blocks are handled by qualified metrology or quality control personnel. Blocks should be stored in a protective case away from temperature extremes, as thermal expansion can affect accuracy. Clean contact surfaces with an appropriate gage block cleaning solution before wringing or use. Do not drop or strike the block, as surface damage will compromise calibration integrity.
