Test Pin M323.218 — single precision test pin, Ø 2.18 mm, ±0.001 mm (Metav IndustryLine)

The Test Pin M323.218 is a single, workshop‑grade precision pin intended for end‑dimension verification and compact gauge assemblies in production and inspection environments.

• Diameter 2.18 mm, tolerance ±0.001 mm
• Length 50 mm workshop version
• Made from special steel
• Supplied in protective case

Precision that supports reproducible end‑dimension checks

The core advantage of this instrument is its measuring accuracy of ±0.001 mm, which provides a reliable reference for tight tolerance work. The ground 2.18 mm diameter establishes a clear nominal dimension while the 50 mm length offers sufficient engagement for many plug, pin and end‑mass applications. Because the component is machined from special steel, dimensional stability under normal workshop conditions is improved, reducing drift between checks. This level of precision makes the item suitable as a reference element in comparative gauging setups and in-process spot checks where small deviations must be detected early.

Compact design for micro‑scale gauging and micromechanics

Classified within the micro measuring range (suitable for tools with a maximum measuring span between 10 and 100 mm), the pin is optimised for confined fixtures, small bores and micromechanical assemblies. The compact geometry lowers the influence of bending and improves handling when fitted into tight gauge housings. For users who assemble or service instruments for watchmaking, small hydraulic components or precision connectors, the combination of minimal footprint and high repeatability supports quicker set‑up times and more consistent results during routine control sequences.

Workshop robustness and protected transport packaging

This workshop edition has been specified for regular use on the shop floor. The construction from special steel and the workshop finish increase resistance to surface wear while keeping the thread and seating geometry stable. Delivery in a protective case safeguards the reference surface and assists safe storage and transport between inspection stations. The case also simplifies traceability in multi‑station operations, allowing the datum pin to be moved without incidental knocks or contamination that would otherwise compromise measurement reliability.

Practical uses and process reliability

Typical applications include acting as an end‑mass for plug gauges, a datum pin for fixture alignment and a wear‑reference in routine production sampling. The pin supports efficient pass/fail decisions in go/no‑go workflows and can be integrated into gauge blocks or small adaptors for comparative checks. Metav IndustryLine’s position as a distributor with an on‑site quality filter for the European market adds an additional layer of assurance: the component is offered within a curated selection intended for industrial users who demand reproducibility and straightforward integration into existing quality control processes.
