Value Collection 630-22006 Steel Gage Block 2 in Grade 0

Product Description

The VALUE COLLECTION 630-22006 is a rectangular steel gage block ground and lapped to Grade 0 accuracy tolerances. Gage blocks serve as dimensional reference standards used to calibrate measurement tools, set comparators, and verify part dimensions on the shop floor or in a metrology lab. This block measures exactly 2.00000 inches and includes a NIST certification document, confirming traceability to national standards. At 0.5 pounds, the block is solid steel construction, delivering the thermal stability and wear resistance expected in a precision reference standard. Licensed metrology technicians, tool-and-die machinists, and quality control inspectors are the primary users.

Grade 0 gage blocks fall within the tighter end of the standard accuracy hierarchy, making this block appropriate for calibration lab use, incoming inspection stations, and toolroom applications where measurement traceability is required. The included NIST certification satisfies quality management system documentation requirements under ISO 9001, AS9100, and similar standards. This block suits both standalone use and integration into a gage block set when a single replacement or supplemental block is needed.

Key Features

• Grade 0 accuracy classification for precision dimensional reference work
• Nominal size of 2.00000 inches for direct use as a 2-inch reference standard
• Steel construction provides durability and thermal stability in shop environments
• Includes NIST certification for measurement traceability documentation
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style replacement or supplemental piece for rectangular steel gage block sets requiring a 2-inch Grade 0 block with NIST traceability.

Installation Notes

Gage blocks are precision instruments and should be handled by metrology technicians or qualified machinists familiar with proper wringing technique. Clean all mating surfaces with an appropriate solvent before wringing blocks together to prevent contamination that can affect accuracy. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Do not drop or stack blocks carelessly, as surface nicks or scratches will compromise accuracy and require recertification.
