Gauge pin M323.403 — 4.03 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

A gauge pin M323.403 designed for precise end‑measurement and go/no‑go checks in workshop inspection and quality control applications

• High‑precision ±0.001 mm tolerance
• 4.03 mm diameter for end‑measurements
• 50 mm hardened length for stable seating
• Workshop execution for daily use

Precision that protects production

With a nominal diameter of 4.03 mm and a declared tolerance of ±0.001 mm, this gauge pin delivers the dimensional certainty required for final inspection and tight‑tolerance assemblies. The 50 mm length provides a stable reference when checking bores, dowel seats or mating parts, reducing ambiguity in go/no‑go assessments. Made from special steel, the pin resists wear under frequent use so that measurement results remain reproducible and process decisions can be made on a solid factual basis.

Designed for robust workshop handling

The workshop execution of this test pin combines a compact form with a surface and hardness profile suited to regular use on inspection benches. As a single‑piece deliverable, it simplifies inventory and replacement routines while its low mass (approx. 0.007 kg) supports quick manual handling during multi‑point checks. The straightforward geometry minimises seating errors and accelerates cycle times during incoming inspection or in‑process verification, translating precision into measurable time savings.

Fits practical quality workflows

Integration into standard inspection procedures is effortless: the gauge pin is ideal for end measurements, alignment checks and functional testing of press fits or dowel holes. Traceability is supported by the clear article identifiers and industry classification included in the technical data, which aids documentation and quality records. Using a dedicated gauge pin with this tolerance level lowers the risk of rework, improves first‑pass yield and stabilises downstream processes — a rational advantage for production teams focused on efficiency and scrap reduction.
