Mitutoyo 614201-531CAL Steel Gage Block 1 in Grade 0

Product Description

The MITUTOYO 614201-531CAL is a square steel gage block sized at 1.00000 inches, manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machining and inspection environments. Grade 0 denotes a tighter accuracy tolerance than Grade AS-1, making this block appropriate for inspection-room and laboratory calibration work. The steel construction provides the durability and stability required for repeated use in dimensional metrology applications. This block meets NIST-traceable standards, supporting documentation requirements in quality management systems.

This gage block is suited for use in tool rooms, quality labs, and production inspection stations. It is commonly used by metrologists, machinists, and quality technicians to calibrate micrometers, calipers, height gauges, and comparator stands. The 1.00000-inch nominal size makes it a standard building block for wringing sets used to produce specific reference dimensions. It is sold and packaged as a single unit.

Key Features

• Grade 0 accuracy for inspection and laboratory-grade calibration work
• 1.00000-inch nominal size, precision-ground steel construction
• NIST-traceable standards compliance for quality documentation requirements
• Square geometry supports wringing with other gage blocks for composite dimensions
• Single-unit packaging for individual replacement or supplemental use

Compatibility

Designed as an OEM-style replacement or supplemental gage block compatible with standard square steel gage block sets requiring a 1.00000-inch Grade 0 steel block.

Installation Notes

Gage blocks are handled and stored by metrology technicians following established laboratory practices. Before use, clean all mating surfaces with an appropriate solvent to remove oils, debris, and oxidation that can affect wringing and measurement accuracy. Store the block in its protective case when not in use to prevent surface damage and corrosion. Do not drop or wring blocks with excessive force, as this can damage the lapped surfaces and compromise calibration integrity.
