M323.256 gauging pin — Workshop gauging pin, 2.56 mm, ±0.001 mm (Metav IndustryLine)

The M323.256 gauging pin is a workshop-grade measuring pin intended for precise end‑measure checks, fit inspection and go/no‑go verification in inspection benches and assembly processes.

• Workshop-grade gauging pin, 2.56 mm diameter
• Ultra-fine tolerance ±0.001 mm
• 50 mm hardened special-steel shank
• Compact length ideal for confined checks

Reliable accuracy for critical fit control

The defining benefit of this gauge is its repeatable accuracy: with a declared tolerance of ±0.001 mm (equivalent to 1 µm) the pin supports highly demanding inspection tasks where tight clearances or press fits are evaluated. Such fidelity reduces uncertainty in pass/fail decisions and helps to cut costly rework cycles in production. The narrow diameter and controlled dimensions make the component suitable for both serial inspection and the final gauging step of a production workflow, where consistent results speed up throughput and improve traceability.

Robust construction tailored to workshop use

Manufactured from special steel, the shank delivers a balance between wear resistance and dimensional stability under routine handling. The 50 mm length is chosen to provide a firm reference while remaining manoeuvrable in confined setups; this makes the gauge well suited to bench fixtures and tight assembly jigs. The workshop specification indicates a design that withstands daily handling and retains form for repeated measurements, offering a dependable tool for quality technicians and machinists who require durability without compromising metrological performance.

Practical application and integration into inspection routines

This measuring pin excels as an end‑measure reference in go/no‑go fixtures, in-line inspection, and spot checks during assembly. Its compact form is advantageous for confined components and for use in comparison inserts or nested fixtures. As a purpose-made inspection element, the pin simplifies decision-making in quality control: a single, precise reference reduces operator variation and supports consistent documentation. For production environments seeking measurable gains in process reliability, this gauge contributes to clearer acceptance criteria and quicker verification cycles.

FAQ

What level of precision does this gauging pin provide?
The M323.256 gauging pin is specified with a tolerance of ±0.001 mm, delivering sub‑micron repeatability suitable for high‑accuracy fit and end‑measure checks.

Can the pin be used in go/no‑go fixtures and nested gauges?
Yes, the compact 50 mm length and accurately controlled diameter make it suitable for integration into go/no‑go fixtures, nested gauges and bespoke inspection inserts.

What material is the pin made from and why does it matter?
The pin is made from special steel, chosen for a balance of wear resistance and dimensional stability so that routine workshop use does not quickly degrade the reference dimension.

Is the M323.256 appropriate for confined or recessed measurements?
Its compact design and short length make the gauge particularly effective for confined spaces and recessed bores where longer references would be impractical.

How does the gauge support process reliability in production?
By providing a consistent reference with tight tolerance, the pin reduces operator variation in pass/fail checks and helps standardise acceptance criteria across inspection points.
