M323.490 Gauge Pin — Single 4.90 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.490 gauge pin is a workshop-grade inspection pin for dimensional checks and end‑mass measurements in production and quality control.

• Workshop-grade construction
• Tolerance ±0.001 mm accuracy
• 50 mm length for deep measurements
• Delivered in protective transport case

Exact control where repeatability matters

The gauge pin is manufactured for measurement tasks that require high repeatability; the ±0.001 mm tolerance guarantees exceptionally small deviation during comparative checks and plug‑gauge references. Where tight fits and end‑mass measurements are part of the process, this precision reduces uncertainty and shortens decision cycles in inspection routines. The result is fewer false rejects and more reliable acceptance testing in series production.

Durable material and workshop readiness

Made from special steel and offered in a workshop‑grade version, the inspection pin resists wear under repeated contact. The chosen material provides a hard, uniform surface that preserves diameter and form over time, ensuring that the nominal diameter remains stable across many measurement cycles. This durability supports consistent measurement results and lowers the frequency of replacements in busy shop environments.

Practical dimensions for deep features

With a nominal diameter of 4.90 mm and a shaft length of 50 mm, this pin reaches into deeper bores and stepped features while maintaining stability during handling. The balanced length-to-diameter ratio reduces the risk of bending during manual positioning and enables straightforward use with micrometre stands, internal comparators or as a reference element in fixture setups.

Efficient workshop logistics and protection

Each unit is supplied individually and delivered in a protective transport case to prevent surface damage during storage and transit. The single‑piece delivery format simplifies stock control for small‑batch tooling, while the transport case supports safe movement between inspection stations without risk to the calibrated surface finish.

Integration into quality workflows

Identifiable by SKU and GTIN, the pin is easy to include in inventory systems and inspection routines. Traceable labelling supports traceability for process documentation and batch control. The compact nature of the item means it can be introduced into established gauging sets or used as an individual reference for go/no‑go checks, assembly controls and dimensional verification tasks.

Reliable choice for workshop inspection

As a focused instrument for end‑mass and bore verification, the inspection pin delivers measurable gains in inspection speed and confidence. Its workshop adaptation, precise tolerance and transport protection make it a pragmatic component for routine quality assurance tasks, helping teams keep measurement throughput and reproducibility high.
