Gauge pin M323.321 – 3.21 mm Ø, ±0.001 mm tolerance, 50 mm length (Metav IndustryLine)

The gauge pin, single, 3.21 mm, ±0.001 mm, 50 mm is a workshop-grade precision pin designed for dimensional verification, end-measure masters and alignment checks in industrial metrology and quality control.

• High-precision ±0.001 mm tolerance
• Workshop-grade construction for regular use
• Diameter 3.21 mm for small-bore verification
• 50 mm length for deeper engagement in fixtures

Precision that minimises uncertainty

The exceptional ±0.001 mm accuracy of this gauge item provides a reliable reference for tasks where tolerances are tight and rework costs are high. Manufactured for metrology applications, the pin serves as a stable reference when checking bore diameters, seating fits or calibrating fixtures. The specified tolerance translates into traceable repeatability on the shop floor, supporting process control and measurement documentation in line with industrial quality demands. This level of precision reduces interpretation error and helps maintain consistent assembly quality.

Built for workshop routines and longevity

Constructed from special steel and finished for workshop use, the pin withstands repeated insertion and withdrawal without rapid wear, preserving measurement integrity over many cycles. The 50 mm length allows access to recessed features and deeper bores while keeping handling straightforward; the item’s low weight (approximately 0.006 kg) aids quick manipulation during inspection sequences. The workshop execution balances toughness with the fine surface finish needed for precise contact, so the pin remains practical for daily quality checks and fixture set-ups.

Versatile applications and straightforward handling

As a single gauge pin, this component is suitable as an end-measure master, for alignment checking in jigs and fixtures, and for spot verification during incoming inspection. Its 3.21 mm diameter is appropriate for small-bore assessment and plug-fit verification in precision assemblies. The compact geometry facilitates use with pin holders, comparator stands or manual gauge kits, and the robust material ensures predictable wear behaviour—important when planning periodic replacement intervals or setting up inspection routines.

FAQ

How precise is the gauge pin and what does the stated tolerance mean?
The gauge pin is specified to ±0.001 mm, which means its manufactured diameter is controlled within one micron; this provides a highly stable reference for precision bore checks and master measurements.

Can the pin be used for alignment in fixtures and jigs?
Yes, the workshop-grade construction makes the pin suitable for alignment tasks in fixtures and jigs where a reliable reference diameter is required for positioning or assembly checks.

What material is the pin made from and why does that matter?
The pin is made from special steel, selected for a balance of wear resistance and surface finish; this supports longevity under frequent use while maintaining measurement fidelity.

Is the 50 mm length suitable for recessed bores?
The 50 mm length gives added reach for recessed or deeper bores compared with shorter pins, enabling repeatable engagement without compromising handling.

Which situations call for a single gauge pin rather than a full set?
A single pin is appropriate when a specific diameter reference is needed for master checks, selective inspection tasks or when integrating a known datum into an existing gauge assembly.
