Test pin M323.831 — precision gauge pin, 8.31 mm, tolerance ±0.001 mm (Metav IndustryLine)

A Test pin M323.831 manufactured for workshop inspection and reference measurements, ideal as a dimensional standard for gauges, fixtures and quick go/no‑go checks.

• Workshop-grade design for rugged use
• Diameter precisely 8.31 mm tolerance ±0.001 mm
• Length 50 mm for end-measurement applications
• Special steel construction for dimensional stability

Accuracy that stabilises production control

The pin offers an exceptional ±0.001 mm tolerance, placing it in the category of high‑precision reference pins for demanding inspection routines. Such a fine allowance corresponds to one micron and therefore permits repeatable comparison measurements against internal diameters, bores or mating parts where small deviations matter. Using a defined reference reduces measurement scatter and supports statistical process control, so inspection steps become reliable inputs for production decisions rather than approximate checks.

Durability tailored to everyday workshop use

Built in a workshop‑grade configuration from special steel, the pin withstands frequent handling while keeping dimensional fidelity. The combination of a compact 50 mm length and a carefully selected material minimises thermal distortions during short measuring cycles and reduces the risk of geometric change through knocks or abrasion. The resulting robustness ensures that the component maintains its role as a stable reference even in routine shop‑floor conditions, extending intervals between verification events.

Practical integration into inspection and setup

As a compact reference element, the pin is suitable for end‑measurement tasks, fixture setup and quick verification of bore sizes. The 8.31 mm diameter and 50 mm length make it convenient for insertion, tactile feel checks and use with bench comparators or optical devices where a defined, hard datum is required. Its narrow form factor eases access into recessed features and permits straightforward placement in gauge blocks or bespoke holders, speeding up both first‑article inspection and corrective alignment procedures.

Procurement confidence and technical partnership

Sourced under the Metav IndustryLine programme, the component benefits from a central European quality filter that assures traceable stock and consistent dimensional specification. Metav’s product range and logistics support reduce procurement complexity for workshops and small manufacturers, so precise measuring aids are available without lengthy supplier qualification. The focus on reliable supply and technical clarity helps integrate such reference pins into structured quality workflows with minimal administrative overhead.
