Gauge pin M323.648 – single test pin, 6.48 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A gauge pin M323.648 intended for precise end‑dimension verification and repeatable inspection tasks in workshop and production environments.

• Workshop version, robust construction
• Diameter 6.48 mm, tolerance ±0.001 mm
• 50 mm overall length for compact inspection
• Supplied in protective transport case

Precision where repeatability matters

This test pin delivers an industrial‑grade tolerance of ±0.001 mm, giving a reliable reference for critical end‑size measurement. The small diameter of 6.48 mm is ideal for narrow bores, gauge fixtures and plug checks where fine clearance must be confirmed. By using a finely finished reference element made from special steel, measurement scatter is reduced and process capability improves; the result is fewer rejects and faster go/no‑go decisions on the shop floor. The compact design also minimises leverage and lateral deflection during insertion, supporting consistent readings across repeated cycles.

Built for workshop handling and long‑term use

Designed as a workshop version, the pin combines a hardened core with a corrosion‑resistant surface to withstand regular handling and contact with mating parts. The modest mass (approx. 0.016 kg) lowers inertia and reduces wear on both the pin and mating components, which extends service intervals and reduces fixture maintenance. Supplied in a protective transport case, the element arrives ready for safe storage and makes it straightforward to keep inspection tools organised between shifts. The robust construction suits routine use in assembly, incoming inspection or quick bench checks.

Integrating into inspection routines and fixtures

With a 50 mm overall length the pin fits most standard checking fixtures and compact inspection rigs without obstructing surrounding features. It functions as a dedicated reference for end‑size checks and final dimensional verification, and its repeatable geometry supports statistical process control routines when logged over time. Where fixture adapters are used, the consistent diameter and finish ensure predictable seating and minimal variation. For labs and workshops seeking stable reference parts for short‑run inspections, this pin is a practical, space‑efficient choice that keeps the focus on measurement quality and process clarity.
