Value Collection 630-73756 Steel Gage Block 0.75 in Grade 0

Product Description

The VALUE COLLECTION 630-73756 is a Grade 0 square steel gage block measuring 0.75 inches, used for dimensional measurement, calibration, and inspection work across machining, tooling, and metrology applications. Grade 0 indicates a high level of dimensional accuracy, making this block suitable for precision measurement tasks where tight tolerances are required. It includes NIST certification, providing traceability to national measurement standards. This type of gage block is a standard reference tool found in machine shops, quality control labs, and tool rooms.

This gage block is designed for use in precision measurement and calibration environments. It is commonly used to set comparators, calibrate measuring instruments, verify part dimensions, and establish reference standards on surface plates. It is appropriate for both production floor and laboratory settings where documented measurement traceability is required. The included NIST certification supports quality system compliance in environments governed by ISO, AS9100, or similar standards.

Key Features

• Grade 0 accuracy for high-precision dimensional reference and calibration use
• Steel construction for durability and dimensional stability over time
• 0.75 inches nominal size with five-decimal precision designation (0.75000 inches)
• Includes NIST certification for measurement traceability
• Square form factor for consistent surface contact and wringing compatibility

Compatibility

Designed as an OEM-style replacement or supplemental reference standard for use in precision metrology sets requiring Grade 0 steel gage blocks with NIST-traceable certification.

Installation Notes

Gage blocks are handled and used by metrology technicians and quality control personnel. Before use, clean contact surfaces with an appropriate solvent and lint-free cloth to remove oils and debris. Store blocks in a protective case away from temperature extremes and humidity to maintain dimensional stability. Do not drop or impact the block, as this can alter its accuracy grade.
