Value Collection 630-71016 Gage Block 0.101 in Grade 0

Product Description

The VALUE COLLECTION 630-71016 is a square steel gage block sized at 0.101 inches, manufactured to Grade 0 accuracy standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on machined parts. This block ships with NIST certification, confirming that its actual size has been measured and documented against national measurement standards. Machinists, quality control technicians, and metrology lab personnel rely on Grade 0 blocks when tight dimensional verification is required on the shop floor or in a calibration environment.

This gage block is suited for use in machine shops, toolrooms, quality labs, and manufacturing environments where precise linear measurement references are needed. It functions as a standalone reference block or as part of a larger gage block set for building up specific dimensions. Typical applications include setting up surface plates, calibrating micrometers and calipers, and establishing reference datums for inspection fixtures. The square form factor provides stable contact surfaces for wringing to other blocks or reference surfaces.

Key Features

• Grade 0 accuracy rating for high-precision dimensional reference work
• 0.101-inch nominal size, ground and lapped to tight tolerance
• Steel construction provides durability and wear resistance in shop environments
• Includes NIST certification documenting traceability to national measurement standards
• Square geometry supports stable wringing and flat surface contact

Compatibility

Designed as a standard square steel gage block for use with conventional gage block sets, holders, and accessories compatible with inch-series precision measurement equipment.

Installation Notes

Gage blocks should be handled by metrology technicians or trained machinists familiar with proper wringing technique and storage procedures. Clean contact surfaces thoroughly before use to remove oils, debris, and burrs that could affect accuracy or damage lapped faces. Store the block in its protective case away from temperature extremes and humidity to prevent corrosion and dimensional drift. Do not drop or stack blocks without proper wringing, as impact damage will compromise calibration integrity.
