Value Collection 630-33206 Steel Gage Block 0.2 in Grade AS-1

Product Description

The VALUE COLLECTION 630-33206 is a rectangular steel gage block ground and lapped to Grade AS-1 accuracy, measuring exactly 0.20000 inches. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set up inspection fixtures, and verify part dimensions on the shop floor or in the metrology lab. This block includes NIST certification, providing a traceable accuracy record required in quality-controlled environments. Grade AS-1 tolerances meet ASME B89.1.9 inspection-grade standards, making this block suitable for calibration and inspection work where high accuracy and traceability are required.

This gage block is used in machine shops, toolrooms, calibration labs, and quality inspection departments. It functions as a reference standard for setting micrometers, height gages, comparators, and other precision measuring instruments. Single-block sets at specific nominal sizes are commonly purchased to replace worn or lost blocks from existing gage block sets, or to supplement calibration setups requiring a specific dimension. Trade professionals including machinists, metrologists, and quality control technicians use these blocks in both production and inspection environments.

Key Features

• Grade AS-1 accuracy meets ASME B89.1.9 inspection-grade tolerances
• NIST certification included for traceable dimensional accuracy
• Steel construction provides durability and consistent surface hardness for wringing
• Nominal size of 0.20000 inches for precise dimensional reference
• Rectangular form compatible with standard gage block holders and accessories

Compatibility

Designed as an OEM-style replacement or supplement for rectangular steel gage block sets using standard inch-series nominal sizes.

Installation Notes

Gage blocks are precision instruments and should be handled by qualified metrology or inspection personnel. Before use, clean all mating surfaces with an appropriate gage-cleaning solution to remove oils and debris that can affect wringing and accuracy. Store blocks in their protective case away from humidity and temperature extremes to prevent corrosion and dimensional drift. Do not drop, stack carelessly, or use gage blocks as mechanical stops or setup shims in production tooling.
