Value Collection 630-21176 Steel Gage Block 0.117 in Grade 0

Product Description

The VALUE COLLECTION 630-21176 is a rectangular steel gage block ground to a nominal size of 0.117 inches and manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on machined parts. This block includes NIST certification, confirming it has been measured and documented against National Institute of Standards and Technology reference standards. It is used by machinists, quality technicians, calibration labs, and tool-and-die shops wherever traceable dimensional reference is required.

This gage block is suited for inspection and calibration work in machine shops, manufacturing facilities, and metrology labs. It functions as a standalone reference block or as part of a larger set when stacking multiple blocks to achieve target dimensions. Grade 0 accuracy makes it appropriate for high-precision inspection work where tighter tolerances are required compared to Grade AS-1 or Grade K blocks. Its rectangular form is the standard geometry for wringing and stacking applications.

Key Features

• Grade 0 accuracy for high-precision dimensional reference and calibration work
• Includes NIST certification providing traceable measurement documentation
• Steel construction for durability and resistance to wear during repeated use
• Rectangular form supports wringing with other gage blocks to build target dimensions
• Nominal size of 0.117 inches precisely ground for reliable reference

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block sets and wringing stacks used in general metrology and dimensional inspection applications.

Installation Notes

Gage blocks are handled and used by calibration technicians and quality inspection personnel. Surfaces should be cleaned with an appropriate solvent and a lint-free cloth before use to remove oils and debris that could affect accuracy or prevent proper wringing. Blocks should be stored in a protective case away from humidity and temperature extremes to prevent corrosion and dimensional drift. Do not drop or stack blocks haphazardly, as surface damage will compromise accuracy and invalidate certification.
