Precision gauge pin M323.400 — 4.00 mm diameter, ±0.001 mm accuracy (Metav IndustryLine)

The Precision gauge pin M323.400 is a single, workshop‑grade test pin designed for end‑dimension verification and quick go/no‑go assessments in small bore and component inspection tasks

• Workshop‑grade construction
• ±0.001 mm tolerance
• Special steel construction
• Supplied in transport case

Consistent tolerances for critical fits

The core benefit of this tool is its high positional accuracy: with a declared ±0.001 mm tolerance the pin supports repeatable decisions in pass/fail checks and dimensional verification. Such a tight tolerance reduces uncertainty when assessing shaft fits, bore diameters or reference gauges, enabling faster inspection cycles and fewer reworks. The compact geometry keeps thermal mass low, which helps to maintain measurement stability during short‑run checks and manual handling.

Durable workshop design for regular use

Manufactured in special steel, the pin is engineered as a workshop version that balances wear resistance with ease of handling. At 50 mm overall length and a nominal diameter of 4.00 mm, the pin is light and easy to position while offering reliable surface quality where contact is required. The robust finish sustains repeated insertions and withdrawals without compromising the contact profile, extending service life in everyday production environments.

Easy to integrate into inspection workflows

Delivered in a transport case, the pin is ready for secure storage and organised tool kits, which simplifies traceability and inventory management on the shop floor. The compact design suits bench inspection, fixture checks and portable measurement rigs; it is also a practical reference element for comparative gauging. A clear article reference (SKU M323.400) and GTIN help to document the item within procurement and quality systems, supporting consistent replacements and audit trails.
