Value Collection 630-70036 Gage Block 0.1003 in Grade 0

Product Description

The VALUE COLLECTION 630-70036 is a square steel gage block ground to a nominal size of 0.1003 inches and rated to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, verify dimensional tolerances, and set up comparators and surface plates. This block carries NIST certification, confirming its dimensional traceability to national standards. Machinists, quality technicians, and metrologists rely on Grade 0 blocks for high-precision inspection work where measurement uncertainty must be tightly controlled.

This gage block is suited for use in quality control labs, tool rooms, and precision manufacturing environments. It functions as a dimensional reference when calibrating micrometers, dial indicators, height gages, and similar instruments. Grade 0 blocks are appropriate for applications requiring tighter tolerances than Grade 1 or Grade 2 blocks, making them a standard choice in inspection departments and calibration facilities.

Key Features

• Ground to 0.1003 inches nominal size for precise dimensional reference
• Grade 0 accuracy rating for high-precision calibration and inspection work
• Steel construction for durability and wear resistance in shop and lab environments
• Includes NIST certification confirming dimensional traceability to national standards
• Square form factor for stable wringing and stacking with other gage blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and accessories used in dimensional metrology and calibration applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and precision machinists. Keep blocks clean and dry before wringing or stacking to prevent corrosion and maintain accuracy. Store in a protective case away from temperature extremes, as thermal expansion affects dimensional readings. Handle with clean gloves or lint-free cloths to avoid contamination from skin oils.
