5.51mm Gauge Pin, Single, ±0.001mm, 50mm Length, Workshop Version - Metav IndustryLine

This compact gauge pin combines ultra‑fine tolerancing with a robust workshop build: ±0.001 mm tolerance on a 5.51 mm diameter and a 50 mm working length ensure reliable end‑dimension checks and repeatable inspection results. Order the gauge pin directly via Metav Werkzeuge or ask our consultants if needed.

Gauge pin M323.551 — precision test pin, 5.51 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Gauge pin M323.551 is a precision test pin designed for end‑dimension verification and rapid go/no‑go checks in production and workshop metrology.

• Diameter 5.51 mm with ±0.001 mm tolerance
• 50 mm length for compact assemblies
• Special steel for wear resistance
• Workshop execution with transport case

Measure critical diameters with guaranteed repeatability

The main strength of this test pin is its high positional accuracy: a diameter of 5.51 mm held to ±0.001 mm provides significantly tighter control than typical workshop gauges. For incoming inspection, assembly checks or final inspection of turned and ground parts, this level of precision reduces uncertainty and supports consistent quality decisions. The compact geometry and low mass contribute to stable contact conditions, improving repeatability in serial checks.

Built for frequent use in workshop environments

Designed as a workshop execution, the pin balances precision and robustness. The 50 mm length is long enough for reach in many fixtures yet short enough to avoid flexing during hand or fixture probing. Supplied in a protective transport case, the item is protected in storage and on the workbench, making it practical for routine inspection tasks in manufacturing cells and tool rooms where handling and movement are frequent.

Material choice that extends service life

Manufactured from special steel, the pin resists wear and surface damage that would otherwise affect dimensional fidelity. The hard, precisely finished tip preserves the nominal diameter over repeated use, maintaining measurement confidence and reducing the need for frequent replacement. For applications where surface finish or lubricant residue is present, the material and finish combination minimises adhesion and eases cleaning between measurements.

Practical benefits for quality control and process stability

Integrating the pin into sampling routines speeds inspection cycles and supports statistical process control: fewer ambiguous measurements mean faster decision loops and lower scrap rates. The combination of a defined nominal diameter, tight tolerance and compact form factor makes the component suitable as a reference gauge in fixture setups or as a go/no‑go element in manual checking. Traceable identification via SKU/GTIN streamlines inventory and calibration records.
