Gauge pin M323.I57 — Inspection gauge pin, 18.57 mm diameter, 50 mm length

The gauge pin 18.57 mm is a precision inspection pin designed for quick bore checks and end-dimension verification in workshop metrology.

• Workshop-grade design for daily use
• Diameter 18.57 mm with ±0.002 mm accuracy
• 50 mm overall length for confined measurements
• Made from special steel for wear resistance

Precision where process control begins

For in-process verification and final-size inspection, the gauge pin delivers a quantifiable benefit: a dimensional stability of ±0.002 mm gives confidence when validating bore tolerances and end measurements. That level of repeatability reduces rework and supports consistent quality decisions on the shop floor. The specification corresponds to fine metrology tolerances, making the pin suitable for quality control tasks that require more precision than standard workshop gauges.

Built to withstand workshop conditions

As a workshop version component, the pin combines measurement accuracy with a construction that copes with everyday handling. The use of special steel provides improved surface hardness and wear resistance compared with untreated steels, extending the lifetime of the measuring face and keeping the reference diameter stable under repeated contact. The compact mass (approximately 0.15 kg) balances rigidity for handling with ease of positioning during quick checks and fixture use.

Compact geometry for tight applications

The 18.57 mm diameter and 50 mm length give access to shorter bores and confined features where longer gauges are impractical. Its dimensions make it an efficient tool for checking end measurements and fit tolerances in assemblies or milled housings. Supplied in a protective transport box, the pin arrives ready for secure storage and reduces the risk of damage during transit, so precision is maintained between deliveries and use.

Practical benefits across production stages

This inspection pin supports fast go/no-go-style assessments as well as measured verification when combined with bench instruments or height gauges. The robust workshop specification and clear dimensional data make the item a pragmatic choice for production lines, maintenance departments and small metrology stations that require dependable, repeatable measurements without complex setup. As part of a broader Metav IndustryLine assortment, it integrates well into standard inspection routines and fixture designs.
