M323.317 Test Pin (Gauge Pin) — 3.17 mm, ±0.001 mm by Metav IndustryLine

The M323.317 is a single workshop‑grade test pin intended for precise end‑measure verification and fixture checking in inspection and assembly applications

• High‑precision ±0.001 mm tolerance
• Ø 3.17 mm nominal diameter
• 50 mm ground length for stable fit
• Workshop‑grade special steel construction

Reproducible measurement performance for process control

A compact gauge pin with a ±0.001 mm tolerance delivers consistently tight clearances that reduce uncertainty in go/no‑go checks and plug gauges. The finely finished diameter supports repeatable seating in bore gauges and checking fixtures, which translates into fewer false rejects and less rework. Highlighting measurable benefits, this component enhances throughput by shortening inspection cycles and improving interchangeability between mating parts.

Compact form that supports handling and fixture design

The combination of a 3.17 mm nominal diameter and a 50 mm body length provides a stable datum for short‑run and serial checks without excessive overhang or flex. Constructed from special steel, the pin resists wear in regular workshop use and maintains cylindrical integrity under repeated insertion. The reduced mass (approx. 0.006 kg) makes the pin easy to position by hand or in automated nests while ensuring the contact surfaces remain true to the intended gauge geometry.

Practical use cases and integration into inspection routines

Designed as a workshop‑grade test pin for end‑measure checks, this gauge pin is suitable for fixture setting, assembly jigs and reference checks in quality control stations. Its narrow tolerance and ground finish make it appropriate where small clearances and consistent fits are critical, for example in hydraulic or pneumatic valve seats, precision connectors and fine mechanical assemblies. The simple geometry enables straightforward incorporation into existing plug gauge sets and modular checking systems, supporting efficient process control.

FAQ

What is the nominal diameter and tolerance of the pin?
The pin has a nominal diameter of 3.17 mm with a tolerance of ±0.001 mm for tight dimensional control.

What material is used for the gauge pin?
The M323.317 test pin is made from special steel chosen for wear resistance and dimensional stability in workshop use.

For which applications is this test pin intended?
This gauge pin is intended for end‑measure verification, fixture setting and assembly checks where small clearances and repeatability are required.

Can the pin be used in plug gauge sets or jigs?
Yes, the M323.317 is suitable for incorporation into plug gauge sets, modular jigs and inspection nests due to its ground finish and compact length.

How does the short length benefit measurement tasks?
The 50 mm body length reduces overhang and the risk of bending during manual handling, improving seating reliability and repeatability in short‑range checks.
