Value Collection 630-30046 Steel Gage Block 0.1004 in Grade AS-1

Product Description

The VALUE COLLECTION 630-30046 is a rectangular steel gage block ground and lapped to a nominal size of 0.1004 inches and certified to Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block includes NIST certification, providing a documented chain of traceability to national measurement standards. It is a single-piece block suited for individual stack builds or as a standalone reference standard. Machinists, quality technicians, and tool-and-die professionals rely on gage blocks like this for accurate, repeatable measurement work.

This block is appropriate for use in manufacturing, machining, and inspection environments where tight dimensional tolerances must be verified. It fits into standard gage block sets or can be used as a standalone calibration reference. Grade AS-1 designates a working-grade block with tightly controlled flatness and parallelism tolerances, making it suitable for general shop use and instrument calibration in both production and quality-control settings.

Key Features

• Nominal size of 0.1004 inches for precise dimensional referencing
• Grade AS-1 accuracy with controlled flatness and parallelism tolerances
• Steel construction for durability and wringing compatibility with other steel gage blocks
• Includes NIST certification for traceable measurement documentation
• Rectangular geometry compatible with standard gage block holders and fixtures

Compatibility

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

Installation Notes

Gage blocks should be handled by a qualified metrology technician or machinist familiar with proper wringing technique and block care. Store blocks in a protective case away from moisture to prevent corrosion on the steel surfaces. Clean blocks thoroughly with lint-free cloth and appropriate solvent before wringing or use. Do not drop or slide blocks across hard surfaces, as this can damage the lapped faces and compromise accuracy.
