Value Collection 630-33306 Steel Gage Block 0.3 in Grade AS-1

Product Description

The VALUE COLLECTION 630-33306 is a rectangular steel gage block measuring 0.30000 inches, manufactured to Grade AS-1 accuracy standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in machining and inspection environments. This block includes NIST certification, providing a traceable accuracy record required in quality-controlled shops and inspection labs. Grade AS-1 represents a high level of dimensional accuracy suitable for tool room and inspection use. The steel construction provides durability and resistance to wear under repeated handling in production or calibration settings.

This gage block is suited for use in machine shops, tool rooms, quality assurance labs, and metrology environments where traceable dimensional references are required. Typical applications include setting dial indicators and comparators, qualifying fixtures, and verifying the accuracy of micrometers and calipers. The 0.30000-inch size fills a common slot in inch-series gage block sets and can be wrung with other blocks to build up composite dimensions. Installation and use is performed by machinists, quality technicians, and metrology professionals.

Key Features

• Grade AS-1 accuracy for tool room and inspection-grade dimensional reference
• NIST certification included, providing a traceable calibration record
• Steel construction for durability and resistance to wear during repeated use
• Rectangular form factor compatible with standard wringing and block-stacking techniques
• Nominal size of 0.30000 inches for precise inch-series measurement buildup

Compatibility

Designed as an OEM-style replacement and standard reference block for inch-series gage block sets used in tool room and metrology applications.

Installation Notes

Gage blocks should be handled by metrology technicians or qualified machinists familiar with proper wringing technique and block care. Before use, clean mating surfaces with an approved gage block cleaning solution and lint-free cloth to prevent contamination and ensure accurate contact. Store blocks in a controlled environment away from moisture and temperature extremes to maintain dimensional stability. Never drop or strike gage blocks against hard surfaces, as impacts can alter geometry and invalidate certification.
