Test pin M323.312 — inspection pin with 3.12 mm diameter and ±0.001 mm tolerance (Metav IndustryLine)

A Test pin M323.312 supplied as a single inspection pin for precise end‑measurements and reference checks in workshop and metrology routines

• Diameter 3.12 mm precision
• Tolerance ±0.001 mm
• 50 mm length, workshop version
• Supplied in transport box

Sub‑micrometre precision for reliable reference checks

The inspection pin delivers a tolerance of ±0.001 mm (1 µm), making it suitable as a reference for final checks and dimensional verification in precision toolrooms. This level of accuracy reduces uncertainty in pass/fail decisions and supports repeatable measurement cycles. The specification is intentionally narrow to provide a stable datum for end‑measurements, ensuring consistent results when used as a master pin in fixture setups or for calibration checks.

Compact, durable design for everyday workshop use

With a 3.12 mm diameter and 50 mm overall length, the pin combines minimal form factor with mechanical resilience. Manufactured from special steel, the pin resists wear during repeated contact and maintains geometric stability under normal handling. The workshop version is optimised for practical use; at approximately 0.006 kg it is easy to position while remaining stiff enough for repeatable contact. Delivery in a dedicated transport box protects the gauge in transit and storage.

Traceable identification and practical applications

Marked by SKU M323.312 and GTIN 4061905056598, the pin integrates straightforwardly into inventory and quality workflows. Typical applications include end‑measure verification, plug‑gauge complements, and use as a reference in assembly jigs where precise end‑dimensions are required. The compact inspection pin is particularly useful in fine mechanical and toolmaking environments, where reliable reference items accelerate inspection processes and support quality documentation.
