Value Collection 630-71426 Square Steel Gage Block 0.142 in

Product Description

The VALUE COLLECTION 630-71426 is a square steel gage block ground and lapped to Grade 0 accuracy tolerances, measuring 0.142 inches in nominal size. Gage blocks are precision reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy on the shop floor or in a metrology lab. This block includes NIST certification, providing a traceable accuracy record required in quality-controlled manufacturing and inspection environments. Grade 0 classification indicates a high level of flatness, parallelism, and surface finish suitable for tool room and inspection-grade applications. The steel construction offers durability and resistance to wear under repeated handling.

This gage block is suited for machinists, quality technicians, and metrologists working in manufacturing, tooling, and precision inspection settings. It functions as a standalone reference standard or as part of a larger gage block set when building specific measurement stacks. Typical applications include calibrating micrometers and calipers, setting snap gages, and establishing reference dimensions for fixture setups. The included NIST certification makes it appropriate for use in ISO 9001 and similar quality management environments where documented traceability is required.

Key Features

• Grade 0 accuracy classification for tool room and inspection-grade measurement tasks
• Nominal size of 0.142 inches for precise dimensional reference
• Steel construction for durability and long-term dimensional stability
• Includes NIST certification for documented measurement traceability
• Square form factor compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style precision reference standard compatible with standard square gage block accessories, holders, and wringing fixtures used in tool room and metrology applications.

Installation Notes

Gage blocks are handled by metrology technicians and precision machinists. Before use, clean all mating surfaces with an appropriate gage block cleaning solution to remove oils and debris that can affect accuracy. Wring blocks together using a slow sliding and rotating motion to achieve proper adhesion when stacking. Store blocks in their protective case when not in use to prevent corrosion and surface damage.
