Test pin M323.451 — workshop test pin, 4.51 mm Ø, ±0.001 mm accuracy (Metav IndustryLine)

A test pin M323.451 designed for precise end‑measurement and quality checks in workshop environments, supplied as a single, durable inspection gauge.

• Workshop design, robust handling
• Diameter 4.51 mm, tolerance ±0.001 mm
• 50 mm length for end‑measurement
• Special steel, high wear resistance

Repeatable end measurements through micrometric accuracy

The core benefit is the extremely fine tolerance of ±0.001 mm (1 µm), which provides repeatable reference values for bore checks, plug gauges and alignment tasks. With a 4.51 mm diameter manufactured to tight limits, this single test pin reduces uncertainty in go/no‑go verification and dimensional spot checks. The result is measurable quality control gains: fewer reworks and more consistent assembly tolerances based on objectively verifiable measurements.

Robust construction for frequent workshop use

Constructed from special steel in a workshop‑grade design, the pin combines wear resistance with handling robustness. The compact 50 mm overall length keeps the pin easy to position in confined fixtures while providing sufficient engagement for end‑face checks. The combination of material choice and practical length supports longer service life under typical workshop conditions, reducing replacement frequency and downtime in production routines.

Simple integration into inspection and setup workflows

As a single‑piece inspection gauge, the pin is suitable for end‑measurement, alignment of mating parts and as a reference during fixture set‑up. Supplied as an individual inspection item, it fits into existing gauge sets or can be used standalone for fast checks during batch runs. The workshop‑oriented design ensures safe handling and straightforward storage in toolboxes or inspection cases, making the pin a practical complement to calipers and micrometre routines.
