M323.440 gauge pin — 4.40 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.440 gauge pin is a workshop‑grade inspection pin designed for precise end‑measurements and verification tasks in jigs, fixtures and quality control routines.

• Workshop‑grade construction
• Diameter 4.40 mm with ±0.001 mm tolerance
• Length 50 mm, special steel
• Supplied in protective transport box

Accuracy that reduces rework and speeds inspection

A confirmed tolerance of ±0.001 mm makes this pin suitable where micrometre‑level certainty is required for end measurements. As a single, hardened measurement pin it provides a stable reference for go/no‑go checks and dimensional verification; the tight specification reduces the need for repeat measurements and helps to avoid downstream rework. The term gauge pin indicates a precision ground cylindrical standard used to check bore sizes or as a datum for comparative checks, so the technical advantage here is straightforward: small deviations are detectable and reproducible.

Built for everyday workshop use

The pin is manufactured from special steel and finished for robust handling in metrology benches and assembly jigs. With a 50 mm shank it balances reach and stiffness, allowing reliable placement without excessive flex. The workshop‑grade specification denotes a focus on durable surface quality and repeatable geometry rather than fragile laboratory finishes. Supplied in a protective transport box, the item arrives ready for safe storage and immediate use, simplifying logistics for maintenance or replacement parts in production environments.

Practical application and handling benefits

Ideal for end‑measurement tasks, the pin serves as a compact inspection standard for single‑point checks and fixture set‑up. The compact diameter of 4.40 mm makes it appropriate for small bores and precision features where larger gauges are impractical. As a single‑item supply it is useful for replacing worn pins in sets or for extending an existing gauge set with a workshop‑optimised spare. Handling is simplified by the modest weight and familiar cylindrical form, which integrates smoothly into existing quality workflows and fixture designs.
