Gauge pin M323.C88 — 12.88 mm diameter, 50 mm length (Metav IndustryLine)

The gauge pin M323.C88 is a precision reference pin intended for end‑dimension verification and fixture alignment in workshop inspection and assembly environments

• Workshop-grade construction
• 12.88 mm diameter for end‑dimension checks
• Tolerance ±0.002 mm for tight inspection
• 50 mm length with compact, rigid design

Repeatable precision for critical inspection

Designed for straightforward insertion checks and reference measurements, this inspection pin delivers repeatable results where small deviations matter. The specified ±0.002 mm tolerance denotes the pin’s permitted deviation from nominal diameter and supports applications requiring close conformity, such as final inspection of turned shafts or plug checks in jigs. By using a dedicated reference pin rather than approximate tools, measurement uncertainty is reduced and downstream rework is minimised. The narrow tolerance also makes the pin suitable for quality control tasks that bridge workshop and production‑line inspection.

Durable construction for routine workshop use

Manufactured from special steel, the pin combines surface integrity with dimensional stability to withstand regular handling and insertion cycles. The 50 mm overall length keeps the pin compact and rigid, simplifying use in tight fixtures and enabling secure seating in pin holders or bushings. The solid construction and workshop specification ensure that the component maintains form under repeated use, supporting consistent contact conditions and stable measurement references. The low mass facilitates quick manual positioning while providing sufficient stiffness for reliable contact with mating parts.

Practical integration into inspection workflows

As a single‑piece reference, the pin functions as an inspection aid for end‑dimension verification, gauge checks and component alignment. Its 12.88 mm diameter matches holders and adaptors designed for metric pin gauges, allowing rapid exchange within existing setups. Where precise seating and repeatability are required, the pin can be used alongside bench fixtures, depth stands or simple height gauges to create fast go/no‑go checks. This simplifies quality routines and concentrates effort on critical features rather than elaborate measuring sequences, improving throughput without sacrificing measurement integrity.

FAQ

What types of checks is this gauge pin designed for?
The gauge pin M323.C88 is intended for end‑dimension verification, plug checks and fixture alignment tasks in workshop and production inspection environments.

How accurate is the pin and what does the tolerance mean?
The pin carries a tolerance of ±0.002 mm, meaning the actual diameter is guaranteed within that band around the nominal 12.88 mm, which supports precise go/no‑go and comparative checks.

What material is used and how should the pin be cared for?
Made from special steel, the M323.C88 should be kept dry and stored to avoid corrosion; routine cleaning and light protective oiling extend service life.

Can the pin be used with standard pin holders and adaptors?
Yes, the 12.88 mm diameter corresponds to holders and adaptors designed for metric pins of that size, enabling quick integration into existing fixtures.

Is this pin suitable for repeated manual checks on the shop floor?
The workshop‑grade construction of the M323.C88 is intended for frequent manual use, offering stiffness and longevity for regular inspection cycles.
