M323.031 test pin — 0.31 mm diameter, ±0.002 mm accuracy (Workshop version)

A M323.031 test pin designed for precise end‑dimension inspection and plug‑gauging tasks in workshop environments.

• Workshop design for daily shopfloor use
• Diameter 0.31 mm with ±0.002 mm accuracy
• Pin length 40 mm, overall length 57 mm
• Made from special steel for durability

Precision where it improves quality control

High‑accuracy measurement starts with reliable reference tools. The 0.31 mm diameter pin with a ±0.002 mm tolerance provides a reproducible datum for fine bore inspection and end‑dimension verification. The stated tolerance indicates the maximum deviation expected from nominal size and therefore defines repeatability for go/no‑go checks and comparator measurements. Specifying such a tight tolerance reduces uncertainty in pass/fail decisions and supports tighter process control in production and inspection routines.

Robust design for everyday workshop use

Built as a workshop execution product, this test pin balances small scale with practical handling. Constructed from special steel, the pin offers resistance to wear while remaining dimensionally stable under normal shop use. The 40 mm pin length and 57 mm overall length give enough engagement for most small‑bore checks while keeping the component easy to manipulate on the bench or in fixtures. The light mass supports quick manual positioning without excessive inertia, helping to speed up repetitive inspection tasks.

Fits into established inspection workflows

The compact geometry makes the test pin straightforward to integrate into plug gauges, setting masters or measuring jigs. Traceable identification via SKU M323.031 and GTIN ensures clear stock management and documentation in quality systems. Using a dedicated test pin for end‑dimension checks streamlines inspection, shortens measuring cycles and reduces the risk of false rejects — a rational improvement that lowers scrap rates and supports consistent production output.
