Gauge pin M323.158 — single gauge pin, Ø 1.58 mm, ±0.001 mm accuracy (Metav IndustryLine)

The gauge pin M323.158 is a workshop-grade cylindrical reference for end‑measure checks and precision fit verification in inspection benches and jig set‑ups.

• Precision diameter 1.58 mm
• Tight tolerance ±0.001 mm
• Length 50 mm for compact checks
• Speciality steel workshop grade

Consistent micrometric accuracy for dependable checks

The ±0.001 mm tolerance places this gauge pin in the sub‑micrometre inspection range, enabling high precision verification where narrow acceptance bands are required. In practical terms, the specified tolerance reduces measurement uncertainty during plug‑gauge comparisons and reference fittings, supporting reproducible results across successive checks. This level of accuracy is particularly valuable when confirming critical end‑measure dimensions or validating small bores against master gauges.

Compact dimensions that aid efficient workshop workflows

With a diameter of 1.58 mm and a length of 50 mm, the pin is purpose‑built for confined geometries and quick interchange on inspection fixtures. The compact form factor means less probe deflection when used as a reference mandrel and improved access in tight assemblies. For assembly lines and toolrooms where throughput and repeatability matter, the small footprint of the pin facilitates rapid functional checks without sacrificing stability or handling comfort.

Robust material choice for frequent use in shop environments

Manufactured from speciality steel and supplied in a workshop configuration, the pin is specified to withstand routine handling and contact testing. The material selection supports surface integrity under repetitive insertion and withdrawal cycles, preserving the gauge geometry that underpins reproducibility. Where long service life of reference tools prolongs calibration intervals and reduces replacement costs, the chosen steel grade offers a balance of hardness and wear resistance suitable for inspection tasks.

Clear applications across inspection and set‑up tasks

Designed as a single gauge pin for end‑measure purposes, the M323.158 is well suited to plug‑gauge checks, alignment references and fixture setup where a precisely defined shaft diameter is required. The pin functions as a reliable control element in dimensional inspection chains, helping to confirm bore tolerances, verify gauge blocks and support small‑part assembly verification. Integration into existing calibration routines or inspection jigs is straightforward, and the compact geometry makes it adaptable to a range of metrology workflows.
