Single gauge pin M323.191 — Workshop version, 1.91 mm, ±0.001 mm

Single gauge pin M323.191 for high-precision verification in production and inspection environments, designed as a compact, workshop-ready measuring organiser for go/no-go and dimensional checks.

• Workshop version for daily use
• Diameter specified at 1.91 mm
• Tolerance ±0.001 mm for tight control
• Delivered in a protective case

Precision where it matters

A compact measuring element with a nominal diameter of 1.91 mm and an accuracy of ±0.001 mm delivers the kind of stability required for fine end‑measurements and calibration checks. The small diameter combined with the close tolerance reduces measurement scatter and supports high repeatability in serial inspection tasks. This design is particularly suited to small‑bore checks, plug tests and fixture set‑up where a defined reference diameter removes ambiguity and shortens inspection cycles.

Robust construction for workshop environments

Manufactured from special steel, the pin is built to withstand handling and routine use without compromising dimensional integrity. The 50 mm overall length provides sufficient engagement for a reliable reference while remaining easy to handle and store. Its workshop version specification balances durability with cost efficiency, and the item is supplied in a protective case to prevent damage during transport and to keep the reference surface clean between uses. This combination supports stable measurement capability across many production runs.

Practical benefits for quality workflows

Integrating a small, precision reference pin into inspection routines simplifies gauge settings and reduces the need for repeated adjustments. The defined tolerance helps to lower scrap rates and shortens process feedback loops, providing a clear reduction in rework and clearer pass/fail decisions on the shop floor. In addition, the compact form factor streamlines storage and handling in busy quality departments, making the pin a practical choice for batch inspection, fixture validation and small‑bore verification tasks.

FAQ

What inspection tasks is this gauge pin suitable for? This single gauge pin is ideal for small‑bore verifications, plug checks and fixture set‑ups where a 1.91 mm reference is required; its ±0.001 mm tolerance supports fine dimensional control.

Is the pin suitable for repeated workshop use? Yes—the workshop version construction and the special steel material provide robust performance for regular handling and routine inspection operations.

How does the pin help reduce measurement uncertainty? By providing a fixed, certified reference diameter and a tight tolerance, the pin improves repeatability and clarity in pass/fail decisions, which in turn reduces measurement uncertainty and lowers rework rates.

Which identifier should be used when ordering or specifying this item? Use the article number M323.191 or the GTIN 4061905055362 when ordering or referencing this gauge pin.
