Value Collection 630-20076 Steel Gage Block 0.1007 in Grade 0

Product Description

The VALUE COLLECTION 630-20076 is a rectangular steel gage block ground and lapped to Grade 0 accuracy tolerances, measuring 0.10070 inches in nominal size. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify part dimensions on the shop floor or in the metrology lab. This block includes NIST certification documentation, confirming traceability to national measurement standards. Grade 0 classification indicates tight tolerance control, making this block appropriate for precision inspection work where measurement uncertainty must be minimized. Machinists, quality technicians, and calibration specialists are the primary users.

This gage block is suited for use in manufacturing environments, tool rooms, and inspection departments where accurate dimensional reference is required. The rectangular steel construction provides durability and resistance to wear under repeated wringing and handling. The 0.10070-inch size fills a common incremental step in gage block sets and can be used as a standalone reference block or combined with other blocks to build composite dimensions. Applications include CMM setup, surface plate work, and calibration of micrometers, calipers, and height gages.

Key Features

• Grade 0 accuracy classification for precision inspection and calibration applications
• Nominal size of 0.10070 inches for incremental dimensional reference
• NIST-traceable certification included with the block
• Steel construction for durability and stable dimensional performance
• Rectangular form compatible with standard wringing techniques

Compatibility

Designed as an OEM-style individual gage block for use in dimensional metrology and inspection applications requiring Grade 0 steel reference standards.

Installation Notes

Gage blocks are handled and stored by calibration technicians and quality inspection personnel, not installed in the traditional sense. Clean mating surfaces thoroughly before wringing blocks together to prevent damage to lapped faces. Store the block in its protective case when not in use to prevent corrosion and surface damage. Follow your facility metrology program guidelines for recalibration intervals to maintain traceability.
