Description

The MITUTOYO 611340-531 is a rectangular steel gage block ground to a nominal length of 0.04 inches and certified to Grade 0 accuracy per ASME standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in a metrology lab. Grade 0 blocks meet tighter tolerance requirements than Grade AS-1 or Grade K, making this block suitable for calibration work and inspection-grade measurement tasks. Machinists, quality technicians, and metrologists are the primary users of individual gage blocks and gage block sets.

This block is appropriate for use in tool rooms, quality labs, and production environments where traceable dimensional references are required. Its 0.04-inch size fills a specific increment commonly needed when building up a stack to a target dimension using wringing technique. The rectangular form factor is standard for single-block and combination stack applications across general machining, grinding, and precision inspection work.

Key Features

Grade 0 accuracy per ASME standards for calibration and inspection-grade use
Nominal length of 0.04 inches ground to tight dimensional tolerance
Steel construction provides durability and wear resistance for repeated use
Rectangular form supports wringing with other standard gage blocks
Sold individually single-block quantity for targeted stack increments

Compatibility

Designed as an OEM-style replacement or supplemental individual block compatible with standard rectangular steel gage block sets conforming to ASME gage block specifications.

Installation Notes

Gage blocks should be handled by a qualified metrologist or quality technician. Clean all mating surfaces thoroughly before wringing to prevent scratching or dimensional error. Store blocks in a protective case away from moisture and temperature extremes to preserve surface finish and accuracy. Do not use gage blocks as mechanical stops or clamps they are precision reference standards only.
