Gauge pin M323.221 – workshop-grade gauge pin, Ø 2.21 mm, ±0.001 mm

A gauge pin M323.221 designed for precise end measurements and go/no-go checking in workshop quality control and inspection tasks.

• Workshop-grade tolerance ±0.001 mm
• Diameter 2.21 mm for precision fits
• Hardened special steel construction
• 50 mm overall length for depth access

Consistent accuracy for production control

Built for tasks where every micrometre matters, this gauge pin delivers a tolerance of ±0.001 mm, which translates into dependable repeatability during frequent checks. That level of precision supports quick acceptance or rejection of mating bores and alignment features, reducing downstream rework and scrap. The stated accuracy is a measurable quality parameter that helps maintain process stability and supports traceable inspection routines.

Robust design that suits everyday workshop use

The shaft is manufactured from special steel, providing a balance of hardness and wear resistance appropriate for shop-floor handling. The 50 mm overall length gives enough reach for many internal depth checks while remaining easy to manoeuvre. A compact, lightweight design means the gauge pin can be used continuously without fatigue, and its workshop specification ensures it withstands regular use in assembly, fixture set-up and incoming inspection operations.

Practical integration into inspection workflows

As a single precision gauge pin, it is suitable for end measurements, plug checking and fixture calibration where close fits must be verified. The small diameter of 2.21 mm is ideal for fine bores and precision components commonly found in tooling, miniature assemblies and calibration tasks. Combined with Metav’s quality assurance, the tool supports a consistent measurement chain and helps create reliable documentation for quality records and audits.
