Precision Gauge Block for Metrology
The Mitutoyo 614165-531 is a square steel gauge block with a nominal size of 0.125 in. It meets ASME Grade 0 tolerance of +/- 0.10 mm for high-accuracy calibration and inspection tasks. The block includes a Certificate of Inspection but no long-form calibration certificate. It is intended for metrology labs and quality-control departments requiring traceable dimensional standards.
Stable Steel Construction
The steel material provides dimensional stability and wear resistance for repeated wringing and measurement cycles. The square face measures 61/64 in by 61/64 in and features a central hole for tie-rod stacking. No thermal or power characteristics apply to this passive precision tool. The block ships new and ready for immediate use in controlled environments.
Replaces Worn or Lower-Grade Blocks
This Grade 0 block upgrades from Grade AS-1, AS-2 or workshop-grade blocks when tighter tolerance is required. It is not for applications needing a long-form calibration certificate or metric nominal sizes. Buyers who need a full calibration data report or a different nominal dimension should select an alternative part.

Questions about this item
How do I wring the 61/64 in faces together without trapping debris?
Clean both faces with lint-free cloth and solvent, slide them together with a slight twist until adhesion holds, then verify zero gap before adding the next block.
What upkeep does the Grade 0 steel block need over time?
Apply a thin film of corrosion inhibitor after each use, store in the supplied case at stable humidity, and send for recalibration at your lab's scheduled interval.
Which tolerance limit appears first during prolonged measurement sessions?
The ±0.10 mm Grade 0 tolerance is the governing limit; thermal drift or handling stress will reach this boundary before any other specification.
