Test pin, single, 2.51 mm, ±0.001 mm, length 50 mm — Metav IndustryLine

A Test pin, single, 2.51 mm, ±0.001 mm, length 50 mm designed for precise end‑dimension inspection and routine gauge tests in workshop environments

• Single test pin, 2.51 mm, tolerance ±0.001 mm
• Workshop version, robust special‑steel construction
• Length 50 mm, suitable for end‑dimension checks
• Supplied in protective transport case

Repeatable micro‑precision for routine inspection

The compact gauge offers sub‑micrometre accuracy with a specified tolerance of ±0.001 mm (1 µm), ensuring that hole and shaft checks remain consistent across repeated inspections. Where measurement certainty reduces rework and speeds quality decisions, the fine tolerance of this probe provides a verifiable reference for go/no‑go comparisons and alignment checks. The slim geometry minimises insertion friction, supporting fast, repeatable handling in production control.

Built to withstand workshop use while remaining easy to handle

Built as a workshop version from special steel, the pin combines corrosion resistance with surface stability under normal operating conditions. At around 0.005 kg, the lightweight body is easy to position by hand or with simple fixtures, while the 50 mm overall length provides sufficient reach for many end‑dimension applications without sacrificing control. Delivery in a protective transport case keeps the gauge safe during storage and transport, reducing the risk of nicks that would affect accuracy.

Integrates into inspection workflows and shortens process loops

Intended for routine dimensional checks, the pin functions as a fixed reference in visual inspection rigs, manual comparators and simple plug gauges. The clear numerical specification — 2.51 mm nominal diameter with ±0.001 mm accuracy — simplifies documentation and traceability in inspection protocols. Using this hardened reference reduces measurement scatter, which in turn lowers rejection rates and supports faster throughput in assembly or quality control stations.

Practical care and application notes for long service life

Handle the probe gently and store it in its case when not in use to preserve the calibrated surface finish. Light cleaning with a lint‑free cloth and a suitable solvent removes debris without abrading the contact area. Avoid hard impacts and prolonged exposure to corrosive environments to maintain the ±0.001 mm performance. For compatibility with measuring equipment, pair the pin with stable fixtures or measuring blocks to make best use of its specified accuracy.
