Value Collection 630-23256 Steel Gage Block 0.25 in Grade 0

Product Description

The VALUE COLLECTION 630-23256 is a rectangular steel gage block measuring 0.25 inches, manufactured to Grade 0 accuracy standards. 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, confirming its dimensional accuracy has been traceable to national measurement standards. Grade 0 blocks are suitable for high-precision calibration and inspection work where tight tolerances are required. Machinists, quality control technicians, and tool room personnel are the primary users of this type of precision reference standard.

This gage block is intended for use in machine shops, quality assurance labs, and tool rooms where precise dimensional verification is required. It serves as a reference standard for setting dial indicators, height gages, snap gages, and similar instruments. The 0.25-inch size is a common increment in standard gage block sets and is frequently used as a standalone reference block for single-dimension verification tasks in both production and inspection environments.

Key Features

• Grade 0 accuracy for high-precision calibration and inspection applications
• Rectangular steel construction for durability and dimensional stability
• 0.25-inch nominal size for versatile use in dimensional verification
• Includes NIST certification confirming traceability to national measurement standards
• Suitable for use with comparators, height gages, and setting instruments

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessories including holders, jaws, and scribers used in metrology and inspection setups.

Installation Notes

Gage blocks are handled and stored by quality technicians and skilled machinists following standard metrology practices. Blocks should be cleaned with an appropriate solvent and wrung together or seated properly before use to ensure accurate measurement. Avoid dropping or stacking blocks on hard surfaces, as impact damage can compromise accuracy. Store in the provided case or a controlled environment to prevent corrosion and dimensional change over time.
