Gauge pin M323.442 — single test pin, 4.42 mm, ±0.001 mm accuracy

The Gauge pin M323.442 is a single, high‑precision test pin designed for workshop inspection and end‑measure verification in metalworking and toolroom environments.

• Single gauge pin 4.42 mm, high precision
• Tolerance ±0.001 mm for micrometre checks
• 50 mm special steel, workshop version
• Supplied in a protective transport case

Consistent measurement accuracy for quality control

The core advantage of this test pin is its ±0.001 mm tolerance, which enables micrometre‑level repeatability for critical dimensional checks. Used as a reference for end‑measure verification, the pin reduces uncertainty when checking bores, dowel fits or plug gauges. The narrow tolerance supports traceable inspection routines and tight process control, making it suitable for tasks where small deviations would lead to assembly or functional faults.

Durable construction for the workshop environment

Manufactured from special steel and specified as a workshop version, the pin balances surface hardness and corrosion resistance to withstand frequent handling. The 50 mm length offers a compact but stiff measuring element that minimises bending during insertion, while the single‑piece design avoids joint‑related errors. Supplied in a protective transport case, the item is protected in transit and during storage between measurement cycles, helping maintain the calibrated geometry over time.

Practical integration into inspection workflows

The test pin is particularly useful for end‑measure tasks, fixture set‑up and quick verification steps on the shop floor. Its compact form factor and clearly defined diameter make it easy to combine with go/no‑go fixtures, comparator setups or manual measurement rigs. The robust tolerance and material choice support repeatable outcomes across shifts, which simplifies documentation in quality records and supports continuous production decisions without frequent reference measurements.
