Gauge Pin M323.403 — precision test pin, Ø 4.03 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Gauge Pin M323.403 is a workshop‑grade precision test pin designed for end‑measure verification, fixture setting and narrow‑tolerance inspection tasks.

• Precision tolerance ±0.001 mm
• Diameter 4.03 mm nominal
• Length 50 mm for fixture setting
• Workshop‑grade special steel construction

Precision that secures repeatable measurements

The M323.403 offers a certified manufacturing tolerance of ±0.001 mm, delivering measurable improvement in repeatability for bench and fixture checks. Such a fine tolerance reduces measurement uncertainty when confirming final dimensions or aligning jigs. The slim 4.03 mm nominal diameter and 50 mm length make this pin well suited for narrow bores, end‑measure comparators and serial inspection probes where consistent contact geometry is required. By using a dedicated test pin rather than improvised gauges, inspection cycles are shortened and non‑conforming parts are identified faster, supporting predictable production output.

Robust construction for everyday workshop use

Built as a workshop‑grade component from special steel, the pin withstands frequent handling and contact without quick wear. The material choice balances hardness and resistance to deformation, so the gauge retains its form under standard inspection loads. The compact mass and balanced design minimise deflection during insertion, which helps maintain dimensional integrity across repeated measurements. Where operators need a durable reference for quick go/no‑go checks or for setting up fixtures, this pin offers a low‑effort, high‑confidence solution.

Practical integration into inspection workflows

This single test pin simplifies integration into manual inspection benches and modular fixtures. Its nominal diameter and standardised length accommodate a wide range of locating and checking setups, reducing the need for custom components. When used alongside micrometres, comparators or plug‑gage arrays, the pin provides a stable datum that supports accurate alignment and reduces setup times. The clear, numerical tolerance specification also facilitates traceability within quality documentation and part acceptance protocols, making it straightforward to include in inspection plans.

Why this pin supports production stability

Selecting a purpose‑made gauge pin like the M323.403 helps to minimise process variation and to stabilise assembly tolerances. The combination of high accuracy, compact form factor and resilient construction means fewer rejects from misalignment and more consistent batch quality. For workshops that demand reliable end‑measurement and quick fixture checks, this pin offers a precise, low‑complexity tool that slots into existing quality routines without requiring elaborate calibration procedures.
