Value Collection 630-33706 Steel Gage Block 0.7 in Grade AS-1

Product Description

The VALUE COLLECTION 630-33706 is a rectangular steel gage block measuring 0.7 inches, manufactured to Grade AS-1 accuracy standards and supplied with NIST certification. 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. The AS-1 grade designation indicates a high level of dimensional accuracy, making this block suitable for demanding inspection and calibration work. Machinists, quality technicians, and metrologists use this type of block as a traceable length reference in both production and laboratory environments.

This gage block is suited for use in machine shops, manufacturing facilities, tool rooms, and quality control labs. It serves as a single-size reference block for calibrating micrometers, calipers, height gages, and comparator stands. The included NIST certification provides documented traceability to national measurement standards, which is required in many ISO-compliant and regulated manufacturing environments. It is sold individually and is compatible with standard gage block wringing techniques used in set-based measurement setups.

Key Features

• Grade AS-1 accuracy for high-precision dimensional reference and calibration work
• Rectangular steel construction provides durability and resistance to wear in shop environments
• Nominal size of 0.7 inches for use as a traceable length standard
• Includes NIST certification for documented measurement traceability
• Single-block format allows standalone use or integration into a gage block set

Compatibility

Designed as an OEM-style replacement or supplemental block compatible with standard rectangular gage block sets and accessories that follow inch-series gage block wringing and stacking conventions.

Installation Notes

Gage blocks are handled and set up by qualified metrology technicians or machinist inspectors. Before use, inspect the gaging surfaces for burrs, nicks, or contamination and clean with an appropriate gage block cleaning solution. Wring blocks together using proper technique to avoid surface damage and ensure accurate stacking. Store the block in its case away from temperature extremes to maintain dimensional stability and protect the certified surfaces.
