Vermont Gage

Vermont Gage 111203000 Pin Gage Minus Class ZZ 0.030in measurement tool

SKU CH-SH9V-NHBPR

Class ZZ no-go pin gauge with 0.0300 in diameter, 0.00020 in tolerance, 10 microinch finish, RC 60/65 hardness, and NIST-traceable certificate

  • Class ZZ No-Go pin gauge provides precise pass/fail inspection
  • Steel construction hardened to RC 60/65 resists wear in repeated use
  • ±0.00020 in tolerance meets Class ZZ accuracy requirements
  • Certificate of Accuracy with NIST traceability validates calibration
  • 10 microinch or better surface finish ensures consistent contact feel

Vermont Gage 0.030in No-Go Pin Gauge

This Class ZZ minus pin gauge measures a precise 0.0300in diameter with a 0.00020in tolerance. It serves quality-control technicians and machinists who must verify that holes do not exceed a minimum size limit. The uncoated steel body reaches RC 60/65 hardness and a 10 microinch surface finish for repeatable contact. A Certificate of Accuracy with NIST traceability is included per ISO 17025 requirements.

Replaces worn or missing Class ZZ minus members

When an existing gauge shows wear beyond the 0.00020in tolerance or a calibration certificate expires, this pin restores the go/no-go inspection capability. The jump is worth it whenever a shop needs a single replacement to complete a set covering the 0.0110in to 0.0605in range rather than buying a full new kit. It plugs the gap without duplicating sizes already in service.

Fits standard pin-gauge handles and trays

The 2in overall length and 0.0005in diameter increment match common Class ZZ storage and handling systems. It frees operators from improvising with oversized or undersized substitutes that risk false passes. No additional calibration hardware is required beyond the supplied certificate. Buyers who need a Go (Plus) member or a different diameter must source those separately.

Questions about this item

What overall length and material must the fixture accommodate for this 0.0300 in pin gage?

The gage is 2 in long and made of uncoated steel hardened to RC 60/65, so the holder must accept a 2 in steel pin of that hardness.

How is the Class ZZ minus pin gage verified during installation, and what step is often missed?

Insert the 0.0300 in pin into the hole; it must not enter. The missed step is confirming the 0.00020 in tolerance and 10 microinch finish with the included NIST-traceable certificate.

When will this pin gage require recalibration or replacement?

Recalibrate per your ISO 17025 quality schedule; replace if wear or damage alters the 0.0300 in diameter beyond the 0.00020 in Class ZZ tolerance.
