Value Collection 630-39166 Steel Gage Block 16 in AS-1

Product Description

The VALUE COLLECTION 630-39166 is a rectangular steel gage block measuring 16 inches, manufactured to Grade AS-1 accuracy. Gage blocks are precision-ground reference standards used to calibrate measurement tools, verify dimensional tolerances, and set up inspection equipment. This block ships with NIST certification, confirming traceability to national measurement standards. Grade AS-1 designates a high-accuracy inspection-grade block suitable for laboratory and quality control environments. Machinists, metrologists, and dimensional inspection technicians working in manufacturing, toolroom, or calibration lab settings are the primary users of this type of gage block.

This block is suited for applications requiring a long-range reference standard, including calibrating height gages, CMM fixtures, and large-scale dimensional inspection setups. Its 16-inch length makes it appropriate for toolrooms and inspection labs that work with larger workpiece dimensions or need to stack blocks to achieve extended reference lengths. The included NIST certification documentation supports quality system requirements under ISO and similar standards frameworks.

Key Features

• 16-inch nominal length with 5-decimal-place precision (16.00000 inches)
• Grade AS-1 accuracy classification for inspection-grade dimensional reference
• Includes NIST certification for traceability to national measurement standards
• Steel construction for durability and dimensional stability
• Rectangular block form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block wringing, holder, and accessory systems used in dimensional metrology and inspection environments.

Installation Notes

Gage blocks should be handled by qualified metrology or inspection personnel. Store the block in its case away from temperature extremes, as thermal expansion affects measurement accuracy. Clean wringing surfaces with a lint-free cloth and approved gage block oil before use. Do not drop or stack improperly, as surface damage will compromise grade accuracy.
