Mitutoyo 611674-531 Gage Block 1.574 in

The Mitutoyo 611674-531 is a rectangular steel gage block with a nominal size of 40 mm, equivalent to 1.574 in. It is manufactured to ASME Grade 0 tolerance and includes a Certificate of Inspection. The block has a face length of 35.00 mm and a face width of 23/64 in. It is supplied without a long-form calibration certificate or a central hole.

Suitable for calibration and inspection

This gage block suits metrology labs and quality-control departments that require a Grade 0 reference standard for calibrating measuring instruments or inspecting precision parts. The steel construction provides stability for repeated use. Buyers who need a long-form calibration certificate or a block with a centre hole for stacking should look at alternative configurations.

Nominal size 40 mm ASME Grade 0

The decisive specification is the nominal size of 40 mm combined with ASME Grade 0 accuracy. This defines the block's role as a high-precision reference standard. Verify that this exact dimension and tolerance grade match your calibration procedure or stack-up requirements before purchase.
