Mitutoyo 611612-531 Gage Block 0.078 in measurement tool

SKU CH-FJ8N-CMYE0

Steel gage block with a nominal size of 2 mm and ASME Grade 0 accuracy for precision calibration

  • Grade-0 accuracy for critical inspections
  • Rectangular steel block resists wear
  • Nominal 2 mm size for precise setups
  • ASME-standard calibration certificate included
  • 30 mm face length aids stable wringing

Precision Gage Block 2 mm Grade 0

Mitutoyo 611612-531 is a rectangular steel gage block with a nominal size of 2 mm. It meets ASME Grade 0 tolerance and is supplied with a Certificate of Inspection. The block has no central hole and is intended for dimensional calibration and inspection tasks.

For calibration labs and inspection rooms

Engineers who need a single 2 mm reference standard with ASME Grade 0 accuracy will find this block suitable. Buyers who require a full set of blocks or a long-form calibration certificate should look at other options.

Nominal size 2 mm ASME Grade 0

The decisive specification is the 2 mm nominal dimension manufactured to ASME Grade 0 tolerance. This defines the block's role as a primary length standard for comparative measurement and gauge verification.

Highlights

  • Grade-0 accuracy for critical inspections
  • Rectangular steel block resists wear
  • Nominal 2 mm size for precise setups
  • ASME-standard calibration certificate included
  • 30 mm face length aids stable wringing

Questions about this item

Will the Grade-0 steel block need periodic recalibration to stay within the ±0.3000 in length tolerance?

Yes, regular recalibration is recommended; the included Certificate of Inspection gives the current deviation so a lab can confirm it still meets ASME Grade 0 limits.

What dimensional limit is reached first when the 2 mm nominal block is wrung repeatedly in a temperature-controlled lab?

The length tolerance of -0.3000 in to 0 in is the controlling limit; width tolerance of -0.2000 in to -0.0500 in is wider, so length drift appears first.

Does the 30.00 mm face length and 23/64 in width generate noticeable heat or noise during all-day measurement sessions?

No, the solid steel gage block has no moving parts or power draw, so it produces no heat or noise regardless of how long it is used.
