Gauge pin, single – 4.78 mm diameter, ±0.001 mm tolerance, 50 mm length by Metav IndustryLine

Gauge pin, single – 4.78 mm, ±0.001 mm, 50 mm length is a compact workshop probe for precision reference and end‑measurement tasks in quality control and production inspection

• ±0.001 mm tolerance for micron accuracy
• 4.78 mm precision diameter for tight fits
• 50 mm hardened shank for repeatable contact
• Workshop execution for everyday industrial use

Reliable micron-level reference for workshop checks

The gauge pin serves as a stable reference element where dimensional certainty matters. Manufactured to a ±0.001 mm tolerance (equivalent to 1 µm), this test pin offers the control required for repeatable go/no‑go and end‑dimension inspections. The extremely fine tolerance reduces measurement uncertainty and shortens inspection cycles, delivering measurable efficiency gains in routine quality checks and incoming part verification.

Robust material and form for frequent handling

Made from special steel and presented in a workshop execution, the pin balances wear resistance with dimensional stability. The 50 mm overall length provides a practical working reach for most fixture and bore checks while keeping the shank stiff under manual handling. This combination of material and geometry minimises elastic deflection during contact measurement, so readings remain consistent even in a busy production environment.

Simple integration into inspection processes

As a single gauge pin with an exact 4.78 mm diameter, it is suitable for use as a reference mandrel, locating pin or plug gauge in assembly jigs and quality benches. The compact format supports quick substitution in test fixtures and handheld checks, reducing downtime between setups. Where traceable reference points are needed within a measurement routine, this pin acts as a reliable mechanical datum to align and verify parts or tooling.

Built for dependable production control and supply reliability

Produced under industrial manufacturing controls, the pin meets the demands of everyday workshop metrology and supports systematic quality assurance. Supplied by Metav IndustryLine through Metav Werkzeuge, it forms part of a wider offering that helps reduce supplier complexity and keeps precision tooling available for the shop floor. The clear specification and rugged design promote confidence in repeated use and replacement planning.
