Gauge pin M323.457 – single precision gauge pin, 4.57 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A Gauge pin M323.457 designed for high‑precision end‑dimension verification and assembly inspection in workshop and inspection environments.

• Extremely tight tolerance ±0.001 mm
• Nominal diameter 4.57 mm
• Length 50 mm for precision checks
• Special steel construction
• Workshop design for robust use

Confidence through measurable accuracy

The core advantage of this test pin is the ±0.001 mm tolerance, which translates into measurable assurance when comparing shafts, bores or mating parts. With such a narrow tolerance band, the pin serves well for go/no‑go checks and final inspection steps where small deviations matter. The tight specification reduces the likelihood of downstream rejects and supports faster decision making on the shop floor. In metrology terms, this level of accuracy places the component among high‑precision gauge elements suitable for critical end‑dimension control.

Geometry optimised for repeatable checks

A nominal 4.57 mm diameter combined with a 50 mm overall length provides a stable probing geometry that balances accessibility and stiffness. The chosen length limits bending while allowing insertion into deeper bores or through‑hole verifications, improving repeatability compared with shorter probes that can be harder to seat consistently. The cylindrical form is machined to deliver concentricity and surface quality compatible with contact gauges, plug gauges and verification fixtures, supporting straightforward integration into existing inspection routines.

Durable construction for daily workshop use

Manufactured from special steel, this gauge pin is finished to withstand regular handling and the mechanical demands of a workshop environment. The workshop design indicates construction choices focused on robustness and long service life rather than delicate laboratory handling. Corrosion resistance and dimensional stability under typical shop conditions help maintain calibration intervals and reduce maintenance downtime. As a result, the measuring item delivers stable reference points for assembly lines, fixture checks and incoming inspection tasks.

Practical application and compatibility

As a dedicated measuring element for end‑dimension and assembly inspection, the pin is suitable for use with bench gauge stands, verification blocks and manual gauge fixtures. Its geometry and material make it appropriate for frequent tactile inspection tasks as well as process control checks in production. The specification aligns with industry practices for precision pins used to verify mating part diameters and to set up go/no‑go sequences in production testing.
