Gauge pin M323.515 — Single precision test pin, 5.15 mm, ±0.001 mm (Metav IndustryLine)

The Gauge pin M323.515 is a single, workshop-grade test pin designed for micrometre-accurate end measurements and bore verification in precision manufacturing

• Dimensional tolerance ±0.001 mm
• Diameter ground to 5.15 mm
• Length 50 mm for stable engagement
• Made from special steel for wear resistance

Consistent precision for critical checks

The core advantage is the ±0.001 mm dimensional accuracy, which allows the pin to serve in high-precision verification tasks where standard checks would not suffice. Ground to a nominal 5.15 mm diameter and supplied as a single unit, the component supports consistent verification of bores and reference gauges. This level of tolerance places the pin in the realm of fine inspection tools used for end-size assessment and helps reduce uncertainty in pass/fail checks, saving rework time and improving process stability.

Material and handling that support reproducible results

Manufactured from special steel, the test pin balances surface hardness and dimensional stability for repeated use. The 50 mm length provides a comfortable engagement depth and neutral handling characteristics; at approximately 0.011 kg it is lightweight enough for routine use while remaining rigid in the clamped or fixtured state. These material and geometry choices reduce wear and preserve the calibrated size over many cycles, contributing to long-term repeatability in production and inspection processes.

Practical integration in workshop workflows

Designed as a single, workshop-version gauge pin, this part is suitable for quick go/no-go checks, alignment tasks and comparative sizing during setup and maintenance. It can be integrated into inspection fixtures or used with dial indicators and optical comparators for cross-checks. The precise nominal size and tight tolerance make it especially useful where end measurements determine assembly fit or tool offsets, ensuring measurable improvements in first-pass yield and setup efficiency.
