Value Collection 630-71436 Gage Block 0.143 in Grade 0

Product Description

The VALUE COLLECTION 630-71436 is a square steel gage block measuring 0.143 inches, manufactured to Grade 0 accuracy standards and supplied with NIST certification. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify tolerances on the shop floor or in a metrology lab. Grade 0 indicates a high level of dimensional accuracy, making this block suitable for inspection and calibration work where tight tolerance verification is required. Installation and use are performed by machinists, quality technicians, and metrology personnel working in manufacturing and precision fabrication environments.

This gage block is suited for use in tool rooms, quality control labs, and production inspection stations. It functions as a length reference standard for calibrating micrometers, dial indicators, height gauges, and similar precision measuring instruments. The NIST certification documents traceability to national measurement standards, supporting quality management systems such as ISO 9001 and AS9100 where documented calibration traceability is required. Single-block use or wringing into a stack with other gage blocks for custom reference dimensions are both standard applications.

Key Features

• Grade 0 accuracy for high-precision dimensional reference and calibration work
• Steel construction provides durability and long-term dimensional stability
• NIST certification included, establishing traceable measurement documentation
• Square geometry allows easy wringing with compatible gage block sets
• Nominal size of 0.143 inches supports a wide range of stack combinations

Compatibility

Designed as an OEM-style replacement or supplemental reference block compatible with standard square gage block sets used in general metrology and inspection applications.

Installation Notes

Gage blocks are handled and used by quality technicians and precision machinists following established metrology practices. Blocks should be cleaned of oils and debris before wringing or use to prevent measurement error and surface damage. Store blocks in a protective case away from humidity and temperature extremes to preserve dimensional stability. Recertify at intervals consistent with your quality management system requirements and applicable calibration standards.
