The MITUTOYO 611212-541 is a rectangular steel gage block manufactured to AS-1 accuracy grade standards and used for precision dimensional measurement and calibration work. At 0.25 inches in overall length, this gage block provides a highly accurate physical reference for verifying measuring instruments, setting comparators, and checking part dimensions on the shop floor or in the calibration lab. Each block ships with a Certificate of Inspection, confirming it has been measured and verified against traceable standards. Metrology technicians, machinists, and quality control professionals rely on gage blocks of this grade for critical measurement tasks where dimensional accuracy cannot be compromised.
This gage block is suited for use in precision measurement environments including manufacturing QC labs, tool rooms, and metrology departments. It serves as a length reference standard for calibrating micrometers, height gages, and other dimensional measuring tools. The 0.25-inch block is a commonly used size in inch-series gage block sets and individual block applications where a specific nominal length reference is required.
Designed as an individual inch-series rectangular gage block suitable for use with standard gage block accessories, holders, and comparator setups requiring a 0.25-inch length reference.
Gage blocks are handled and used by metrology technicians and precision machinists in controlled measurement environments. Blocks should be cleaned of oils and debris using an appropriate gage block cleaning solution before and after use. Store in the protective case when not in use to prevent corrosion and surface damage. Avoid dropping or contacting the measuring faces against hard surfaces, as this can affect accuracy.
