M323.231 Precision Gauge Pin — Ø 2.31 mm, ±0.001 mm

The M323.231 is a single precision gauge pin designed for end‑measurement checks and fine workshop metrology, offering micrometre‑class repeatability for fixture checks and go/no‑go routines

• High-precision Ø 2.31 mm, tolerance ±0.001 mm
• Length 50 mm for consistent end‑measure checks
• Made from special steel for workshop durability
• Delivered in protective transport case

Micrometre accuracy where small tolerances matter

The pin delivers an ±0.001 mm tolerance, equivalent to 1 µm, making it suitable for demanding reference and end‑measure tasks where microscopic deviations affect fit and function. Such resolution supports tight assembly tolerances and reduces uncertainty in repeat dimensional checks. Measuring pins with this level of precision serve as a stable reference during inspection runs and set‑up procedures, helping to reduce rejects and rework in small‑component production. The compact diameter makes the item ideal for precise alignment or verification of small bores and locating features.

Built for the workshop: ruggedness without compromise

Constructed in special steel with a workshop specification, this test pin balances wear resistance with dimensional stability under everyday handling. The 50 mm length provides a practical reach for many end‑measurement situations while remaining easy to handle and store; the item’s low mass contributes to negligible thermal lag during short inspections. Delivery in a protective transport case safeguards the finished gauge during storage and transport, preserving the ground surface and dimensional integrity until the next inspection cycle.

Integrates simply into inspection processes

As a single test pin, the component serves as a precise reference for plug‑and‑play checks in benches, fixtures and comparator setups. Its consistent diameter and tolerance reduce set‑up time for repetitive checks and improve traceability of measurement routines when used as a master reference in control charts. The straightforward geometry simplifies cleaning and inspection and makes the pin compatible with common gauge holders and locating sleeves used in small‑part metrology. Reliability in day‑to‑day use translates directly into smoother production flow and fewer inspection‑related delays.
