Gauge pin M323.439 — workshop version, 4.39 mm, ±0.001 mm (Metav IndustryLine)

The Gauge pin M323.439 is a hardened end‑measure pin designed for dimensional checking and fixture set‑up in workshop inspection and assembly tasks

• Workshop-grade construction
• Tolerance ±0.001 mm for micrometric checks
• 50 mm hardened length for stable handling
• Delivered in protective transport case

Precision that supports repeatable inspection

The workshop pin delivers a tolerance of ±0.001 mm, which places it in the micrometric class required for high‑precision end‑measure tasks. With a nominal diameter of 4.39 mm, the pin is suitable for bore verification, limit gauges and comparative checks where tight clearances must be proved. The special steel construction ensures dimensional stability under normal workshop conditions and resists minor impacts, so measurements remain reproducible across repeated cycles. This level of accuracy reduces rework and supports consistent quality control routines.

Robust handling for everyday workshop use

A 50 mm hardened length provides sufficient grip and support in clamping fixtures while keeping the contact geometry compact for confined spaces. The workshop version specification prioritises durability and practical handling: the shaft geometry resists bending under handling loads and the overall mass (0.008 kg) contributes to an easy‑to‑manipulate feel during set‑up. Supplied in a protective transport case, the pin arrives ready for secure storage and safe transfer between workstations or to a measuring bench, lowering the risk of damage before use.

Fits routine inspection and fixture tasks with low setup overhead

Designed primarily as an end‑measure reference, the pin integrates into GO/NO‑GO checks, pin gauges and fixture alignment procedures. Its compact diameter and fixed length simplify setup times: once a reference point is established, repeat measurements are fast and comparable. The tool supports workshop productivity through clear, objectively comparable values that feed into statistical process control without extra interpretation. For specialised applications or batch verification, Metav Werkzeuge can advise on complementary accessories and handling aids to streamline inspection workflows.

FAQ

What applications is this gauge pin suitable for?
The gauge pin M323.439 is intended for end‑measure checks, bore verification and fixture set‑up in workshop inspection tasks where a 4.39 mm reference is required.

How precise is the measurement and what does ±0.001 mm mean?
A declared tolerance of ±0.001 mm for the M323.439 indicates micrometric repeatability; this means the pin’s diameter stays within one thousandth of a millimetre around the nominal value during manufacture and initial inspection.

Is the gauge pin supplied ready for storage and transport?
Yes, the pin is supplied in a protective transport case to reduce handling damage and to simplify safe storage when moved between workstations.

Can this pin be used in standard pin holders or fixtures?
The M323.439 is compatible with common fixture and pin holder systems used in workshop gauging; for specific holder dimensions or bespoke fixturing, consult Metav Werkzeuge for recommendations.
