Value Collection 630-31046 Steel Gage Block 0.104 in AS-1

Product Description

The VALUE COLLECTION 630-31046 is a rectangular steel gage block ground and lapped to Grade AS-1 accuracy, making it a dependable reference standard for precision measurement work on the shop floor or in a calibration environment. At 0.104 inches nominal size, this block carries NIST certification, confirming that its dimensional accuracy has been verified against national standards. It is used by machinists, quality technicians, and metrologists to calibrate measuring instruments, set comparators, and verify part tolerances. The steel construction provides the durability and wear resistance expected in a working gage block.

This gage block is suited for use in manufacturing, tool rooms, and quality labs wherever a certified, traceable reference dimension is required. Its Grade AS-1 tolerance classification meets the requirements for inspection-grade applications in general industrial and precision machining environments. The 0.104-inch size is a standard increment used when building up stacks or verifying specific step dimensions on workpieces. Each block ships individually and is ready for immediate use upon receipt of the accompanying NIST certification documentation.

Key Features

• Grade AS-1 accuracy classification for inspection-grade dimensional reference
• NIST certification included, providing traceable calibration documentation
• Steel construction for wear resistance and long service life
• Rectangular form compatible with standard gage block accessories and holders
• 0.104-inch nominal size for use in block stacking or standalone gauging setups

Compatibility

Designed as an OEM-style replacement or supplemental addition to rectangular steel gage block sets requiring a Grade AS-1, NIST-certified 0.104-inch block.

Installation Notes

Gage blocks are handled and set up by machinists and quality technicians, not requiring electrical or mechanical installation. Before use, clean block surfaces thoroughly with an appropriate solvent to remove protective oil and prevent measurement error. Store blocks in their case when not in use to avoid surface damage and corrosion. Do not wring blocks together without clean, undamaged surfaces, as contamination or nicks will compromise accuracy.
