Value Collection 630-73206 Steel Gage Block 0.2 in Grade 0

Product Description

The VALUE COLLECTION 630-73206 is a square steel gage block sized at 0.2 inches, manufactured to Grade 0 accuracy standards. Gage blocks serve as precision length references used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances on machined parts. This block carries NIST certification, confirming its dimensional accuracy has been validated against national measurement standards. It is a single-piece block intended for use in tool rooms, quality control labs, and production environments where reliable, traceable measurement references are required. Machinists, metrologists, and quality technicians are the primary users of this type of tooling.

This gage block is suited for applications requiring a 0.2-inch reference standard at Grade 0 precision. Grade 0 represents a high level of dimensional accuracy, making it appropriate for inspection and calibration tasks where tighter tolerances must be confirmed. It is used in both shop-floor and laboratory settings across manufacturing, machining, and precision engineering trades. The included NIST certification provides traceability documentation necessary for quality system compliance in regulated environments.

Key Features

• Grade 0 accuracy rating for high-precision measurement reference applications
• 0.2-inch nominal size for use as a calibrated length standard
• Steel construction provides durability and resistance to wear during repeated use
• Includes NIST certification for traceable dimensional validation
• Square block format for stable positioning on surface plates and in fixtures

Compatibility

Designed as a standard gage block reference for use with comparators, height gages, and other precision measuring instruments requiring a traceable length standard.

Installation Notes

Gage blocks are precision instruments and should be handled by qualified metrology or toolroom personnel. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Clean block faces with a lint-free cloth and an appropriate solvent before wringing or referencing. Avoid dropping or stacking blocks improperly, as surface damage will compromise accuracy and invalidate certification.
