Gauge pin, single, 2.56 mm, ±0.001 mm — 50 mm length (Metav IndustryLine)

The Gauge pin, single, 2.56 mm, ±0.001 mm, length 50 mm is a workshop‑grade test pin for precise end‑measure inspections, plug and bore checking, and gauge setting in production and maintenance environments

• Workshop‑grade construction
• Diameter 2.56 mm ±0.001 mm
• 50 mm overall length for deep reaches
• Made from special steel

Precision where small deviations matter

Designed for applications that demand sub‑micrometre reliability, this compact test pin brings repeatable accuracy to routine checks. The diameter 2.56 mm combined with a tolerance of ±0.001 mm (one micrometre) ensures reliable fit‑up verification and end‑measure confirmation. In practice, that level of precision reduces setup time for inspection routines and lowers the risk of assembly rejects by providing a consistent physical reference for gauges and small bores.

Robust build for workshop use and longevity

Manufactured in special steel, the test pin resists wear and preserves the working diameter through repetitive use. The workshop‑grade execution prioritises handling and resilience over ultra‑fragile lab finishes, so the pin endures frequent insertion and removal in jigs, fixtures and inspection benches. The compact 50 mm shaft length balances reach and stiffness, keeping measurements steady without unnecessary flex.

Efficient tool for quality control and gauge setting

As a single gauge pin with a clearly defined nominal size and tolerance, this component streamlines go/no‑go workflows and manual gauge setting tasks. Where small bores or precise clearances are inspected, the pin serves as an objective reference that complements optical and dimensional checks. Its slim profile is ideal for confined geometries and end‑measure verification of small components, helping to accelerate routine checking and maintain consistent production quality.
