Gauge pin M323.391 — 3.91 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A gauge pin M323.391 designed as a single precision pin for end‑measurements, fixturing and reference checks in workshop and inspection environments.

• Diameter 3.91 mm precision
• Tolerance ±0.001 mm
• Length 50 mm workshop version
• Delivered in transport case

Accurate references for repeatable inspection results

The compact pin delivers a clear measurement advantage where repeatability matters: a 3.91 mm diameter with an accuracy of ±0.001 mm provides a stable reference for end‑measurements and repeat gauging operations. In practice this tight tolerance reduces uncertainty in fixture alignment and assembly checks, translating into fewer rejects and less rework. The dimensional specification is directly relevant to metrology routines and fixture set‑up, making the component suitable as a go‑to reference in precision inspection workflows.

Robust design geared to workshop handling

Manufactured in special steel and offered in a workshop version, the pin balances dimensional control with everyday usability. At 50 mm overall length the pin is long enough for secure seating in many jigs while remaining compact for easy handling and storage. The modest mass supports rapid placement and removal during repetitive checks without excess inertia, which helps to keep cycle times low on the shop floor. Delivered with a transport case, the component stays protected between uses, maintaining its measured condition over time.

Practical applications and integration into workflows

This precision pin is intended primarily for end‑measurement tasks, fixturing, datum setting and as a reference mandrel during assembly and inspection. Its single‑pin format makes it straightforward to integrate into gauge sets, fixture nests or coordinate measuring arrangements that require a defined, stable reference dimension. For broader metrology strategies, the pin's specification allows planners to slot it into existing inspection sequences, where it serves as a reliable datum for height, bore or depth verification without the need for extensive recalibration routines.
