Test pin M323.789 — precision inspection pin, Ø 7.89 mm, ±0.001 mm (Metav IndustryLine)

Test pin M323.789 serves as a single, high‑precision inspection pin for end‑measure verification and reference gauging in workshop and inspection environments.

• Precision tolerance ±0.001 mm
• Diameter Ø 7.89 mm for end‑measure fits
• 50 mm hardened special‑steel shaft
• Workshop version with transport case

High precision for reference measurements that must be reproducible

The inspection pin delivers a tight tolerance of ±0.001 mm, making it suitable where repeatable end‑measure checks are required. As a compact, single‑piece gauge, it offers a defined contact geometry that reduces measurement ambiguity when used as a reference or plug for small bores and locating features. The combination of Ø 7.89 mm diameter and a 50 mm shaft length gives a stable probe point while keeping handling and fixture integration straightforward. This level of precision supports consistent pass/fail decisions during quality control.

Robust workshop design for everyday handling and fixture use

Made from special steel and finished for workshop duty, the probe resists wear during frequent insertion and extraction from jigs or bores. Its light overall mass (approx. 23 g) reduces the risk of disturbing delicate set‑ups, while the hardened shaft maintains roundness and repeatability over many cycles. Delivered in a transport case for protected storage and transit, the article is configured for reliable use at the bench or in fixture stacks, shortening downtime and simplifying handling during routine inspection rounds.

Practical applications and procurement confidence

Ideal for end‑measure and reference tasks, the gauge pin integrates with plug‑gauge checks, alignment fixtures and depth or step references in assembly operations. The compact geometry suits confined spaces where a defined contact tip is required, while the industrial finish eases cleaning and maintenance. Backed by Metav’s quality approach and broad product range, the component supports standardisation across workshop tool cabinets and inspection benches, helping to reduce supplier overhead and improve part‑to‑part comparability.
