Gauge pin M323.397 — precision plug gauge, Ø 3.97 mm, ±0.001 mm

The M323.397 gauge pin is a single precision test pin for reliable end‑dimension inspection and reference checks in workshop metrology.

• Workshop‑grade precision plug pin
• Diameter 3.97 mm with ±0.001 mm tolerance
• 50 mm overall length in special steel
• Supplied individually for accurate end measurements

Precision where tolerance directly reduces rework

The core advantage of this gauge pin lies in its combination of a fine diameter and a tight tolerance: 3.97 mm with ±0.001 mm ensures that positional and fit checks are performed to an accuracy level that prevents downstream assemblies from failing. In production and quality control environments, that level of repeatability shortens inspection cycles, reduces rework and supports faster sign‑off of incoming inspection or in‑process checks. The compact geometry makes the pin suitable for confined bores and tight end‑measurements while retaining tactile stability.

Robust workshop design for everyday metrology tasks

Constructed from special steel and finished for practical handling, this test pin is designed as a workshop‑grade tool that tolerates regular use without compromising dimensional integrity. With an overall length of 50 mm and a mass consistent with handheld inspection tools, it integrates well into bench setups, gauge sets or bespoke fixture assemblies. The single‑piece delivery format keeps inventory flexible — the tool can be used as a reference gauge for go/no‑go verification, alignment aids or end‑dimension validation during part set‑up.

Integrates into inspection workflows and jigs

As a standard precision pin, the M323.397 is compatible with typical measurement rigs and tactile gauging procedures. Its decisive tolerance simplifies decision rules in inspection plans: a measured mating clearance outside the ±0.001 mm window signals immediate corrective action. When used as a reference element in fixtures, the consistent diameter supports repeatable positioning and minimises cumulative stack‑up errors. This measurable reliability is especially valuable in short batch runs and sampling plans where each measurement must be defensible.

Practical information for QA and traceability

The pin is supplied individually and is identified by SKU M323.397, enabling straightforward stockkeeping and traceability in quality documentation. For processes that require documented traceability, the clear specification of diameter, tolerance and material supports consistent reporting in inspection protocols. The pragmatic construction of this plug gauge means it can be stored alongside other workshop gauges and introduced into standard checks without special handling or dedicated fixtures.
