M323.340 Gauge Pin (3.40 mm) – ±0.001 mm tolerance, 50 mm length, Metav IndustryLine

The M323.340 gauge pin is a workshop‑grade precision inspection pin designed for tight‑fit checks and end‑measure verification in production and quality control environments

• Workshop-grade precision inspection pin
• Diameter 3.40 mm for tight fit checks
• Tolerance ±0.001 mm for micrometre accuracy
• 50 mm hardened special steel construction

Precision where micrometres decide

A compact inspection pin with a 3.40 mm nominal diameter and ±0.001 mm specification enables highly reliable pass/fail checks for small bores and mating parts. The fine tolerance corresponds to micrometre‑level control and reduces uncertainty when validating end dimensions or verifying tooling fits. In practical terms, the small diameter and tight tolerance make this instrument suitable for precision assembly, inspection fixtures and verification of final measures on turned or drilled components. The design supports straightforward use in repeatability tasks where consistent contact geometry and minimal deformation are essential.

Built for repetitive workshop use

Constructed as a workshop‑grade item from special steel, this inspection pin balances handling ease with dimensional stability. With a 50 mm overall length, the pin grants sufficient reach for many standard checks without unnecessary leverage that could compromise repeatability. The low mass aids manual placement while the robust material withstands routine use in production areas. As a single‑piece precision pin, it streamlines inspection workflows where frequent insertion and withdrawal are required, helping to maintain consistent measurement conditions and reduce rework caused by uncertain fits.

Practical application and measurement benefits

In application, the gauge pin functions as a reliable reference for bore checks, end‑measure verification and fixture validation. Used with simple go/no‑go assemblies or as a reference in jigs and gauges, the pin helps shorten inspection cycles and contributes to stable process control. The precision offered by the specified tolerance supports tighter acceptance criteria and fewer downstream adjustments, improving overall production yield. Routine good practice includes gentle handling, clean‑room‑free storage and periodic verification against calibrated references to preserve the stated accuracy.

FAQ

What materials is the M323.340 suitable for inspecting?
The M323.340 gauge pin (Metav IndustryLine) is primarily a dimensional reference for metallic and machined bores; material compatibility is determined by the workpiece rather than the pin itself.

How significant is the ±0.001 mm tolerance in everyday inspection?
A tolerance of ±0.001 mm places the inspection pin in the micrometre class, allowing the M323.340 to serve where high repeatability and tight acceptance limits are required in precision manufacturing.

Is the M323.340 intended for production or laboratory use?
The M323.340 is a workshop‑grade inspection pin designed for routine shop‑floor and production checks while still offering the precision needed for stringent quality control tasks.

How should the gauge pin be maintained to preserve accuracy?
Regular cleaning, avoidance of impacts, and storage in a dry, clean environment are recommended for the M323.340; periodic verification against calibrated standards will ensure continued performance.

Can the M323.340 be used in fixture or jig assemblies?
Yes, the M323.340 gauge pin (Metav IndustryLine) is suitable as a fixed reference or removable checking element in fixtures and jigs where consistent contact geometry is required
