Gauge pin M323.333 — single 3.33 mm reference pin, ±0.001 mm precision (Metav IndustryLine)

The gauge pin M323.333 is a single reference pin for high-precision fit checks and go/no-go control in workshop metrology.

• Precision fit ±0.001 mm tolerance
• Diameter 3.33 mm, length 50 mm
• Workshop version with transport case

Dependable reference for small diameters

A compact reference element designed for repeatable fit checks, the gauge pin offers ±0.001 mm tolerance, equivalent to 1 micrometre accuracy. This level of precision supports critical go/no-go tests and dimensional checks where small clearances matter. The small diameter combined with a 50 mm usable length allows secure engagement in bore and pin gauge applications while keeping handling and alignment straightforward. When measurement uncertainty must be reduced, the micrometre-class tolerance of this reference element provides a clear technical basis for pass/fail decisions in production.

Built for everyday workshop use

The workshop-grade finish and special steel construction give the pin both wear resistance and stable geometry during routine handling. Delivered in a transport case, the item is optimised for safe storage and movement between workstations without exposing the reference surface to damage. At approximately 0.006 kg, the pin is lightweight for manual positioning yet solid enough to resist minor knocks during inspection tasks. These attributes ensure usability during busy shift work and reduce downtime caused by damaged reference tools.

Clear technical role within inspection workflows

This reference pin functions as a proven tactile standard for establishing fits and clearances; it is suitable as a reference for plug gauges, fixture alignment and comparative checks against a precision caliper or an optical comparator. The single-item design favours focused verification steps where one exact diameter is required for repetitive checks. Because the tolerance is specified to ±0.001 mm, interpret results with the corresponding measurement uncertainty of the measuring instrument; precision instruments with sub-micrometre resolution are recommended when exploiting the full accuracy potential of this reference pin.

Integration with quality and procurement strategies

As a compact, high-precision component, the pin supports lean inspection setups and simplifies spare-part lists for small-bore inspections. Sourced via Metav IndustryLine, the product fits into a broader supply strategy that emphasises accessible precision: centralised procurement from Emmerich reduces supplier complexity while maintaining a quality filter for the European market. The combination of a robust material choice and protective packaging makes the item a practical addition to maintenance kits and inspection benches alike.

FAQ

What is the primary purpose of this pin?
The gauge pin M323.333 serves as a fixed-diameter reference for fit checks, plug-gauge comparisons and small-bore inspection tasks in workshop metrology.

How precise is ±0.001 mm in practice?
A tolerance of ±0.001 mm corresponds to 1 micrometre; this precision level is suitable for high-accuracy fit verification where sub-micrometre deviations are relevant.

Is this pin suited to daily workshop handling?
Yes — the workshop version is designed for routine use and is supplied in a transport case to protect the finished surfaces during storage and movement.

What does the material specification imply for wear?
Constructed from special steel, the pin offers improved surface stability and wear resistance compared with softer steels, making it appropriate for repeated mechanical engagement.

Can the pin be used alongside calipers and comparators?
The reference pin is compatible with tactile and optical inspection methods; it is commonly used as a reference when comparing results from a precision caliper or an optical comparator.
