Gauge pin M323.446 – single test pin, Ø 4.46 mm, tolerance ±0.001 mm

Gauge pin M323.446 serves as a compact, high-precision checking pin for end-dimension and assembly verification in workshop and production inspection tasks.

• High precision tolerance ±0.001 mm
• Diameter 4.46 mm for precise gauging
• Length 50 mm, workshop version

Accurate checks for repeatable inspection results

The single gauge pin delivers repeatable measurement performance through its tight ±0.001 mm tolerance, making it suitable for fine end-dimension verification and reference checks. This level of accuracy corresponds to sub-micron shifts being detectable across successive measurements, which supports process stability and traceable inspection routines. The modest diameter of 4.46 mm and a standard 50 mm length allow use in confined features and stack-ups, while contributing to short setup times and reduced measurement uncertainty in routine checks. The result is a measurable improvement in quality control throughput and documentation consistency.

Workshop-proof material and handling benefits

Manufactured from special steel, the pin combines surface hardness with dimensional stability to withstand frequent insertion and contact without rapid wear. The workshop specification ensures robustness for daily use on benches and in fixtures, reducing replacement frequency. At approximately 0.008 kg, the component is easy to handle and integrates well into manual gauges or quick-check rigs. The compact form factor facilitates storage and transport between inspection points while maintaining the geometric integrity expected from precision metrology components.

Integration into inspection workflows and practical advantages

Designed for straightforward use in go/no-go checks, assembly verification and comparative gauging, the pin speeds up inspection steps and reduces measurement variability when used as a reference in jigs or fixture-based checks. Its consistency in diameter and length supports alignment tasks and end-mass (end-dimension) assessments on small components. Traceability is facilitated by the clear article identification and industry-standard format, enabling easy inventory management and replacement planning within manufacturer or supplier-controlled quality systems. The overall effect is improved process reliability and fewer downstream reworks.
