Test pin M323.487 – precision gauge pin, 4.87 mm diameter, ±0.001 mm

The Test pin M323.487 is a single gauge pin designed for end‑measure checks and tight‑tolerance inspection tasks in workshop and inspection environments.

• High precision 4.87 mm diameter
• Tight tolerance ±0.001 mm
• Robust workshop execution
• 50 mm working length

Accurate control for end‑measurement and fit verification

A gauge pin with a 4.87 mm nominal diameter and ±0.001 mm tolerance offers micrometre‑level repeatability for plug gauges, alignment checks and final dimensional validation. The extremely tight tolerance reduces uncertainty in fit verification and minimises rework by ensuring parts meet intended clearance and interference specifications. In practice, this level of accuracy supports reliable assembly checks where component interchangeability is critical; the gauge pin functions as a deterministic reference for go/no‑go assessments and serial inspection routines.

Built for workshop environments with durable material selection

Manufactured in special steel, the component is engineered for repeated use under production conditions. The workshop version construction prioritises surface integrity and wear resistance so that nominal diameter and tolerance remain stable over many cycles. When used in jigs, fixtures or bench measuring setups, the pin maintains dimensional stability and tactile feedback, helping inspection personnel and machine operators make confident, reproducible assessments without frequent replacement.

Practical handling and integration into inspection workflows

The 50 mm length gives sufficient engagement for stable seating in bore and alignment checks while remaining compact for handheld or fixture use. The part’s modest mass (approx. 0.01 kg) simplifies handling during rapid measurement sequences and reduces the risk of accidental damage when inserted or removed. Compatibility with standard gauge sets and inspection jigs makes the pin a pragmatic choice for workshops seeking to streamline measurement routines without investing in bespoke tooling.

Where precision meets production reliability

Intended as a straightforward reference element, the pin complements existing metrology equipment and strengthens quality gates at final inspection and assembly. The component’s classification within micro‑range inspection tools emphasises its suitability for fine mechanical parts and precision assemblies. Proven traceability of dimensions and the pronounced ±0.001 mm specification together lower measurement risk and support consistent product quality across batches.
