Precision where small tolerances matter

A compact measuring element delivers reliable, repeatable checks when manufacturing tolerances are tight. The M323.I91 gauge pin features a Ø 18.91 mm nominal diameter combined with a declared ±0.002 mm deviation, which provides measurable assurance for final‑dimension inspections. Classified in the micro range (measurement span within 10–100 mm), this size is ideal where short jaws and minimal deflection are beneficial: fine mechanical parts, small bores and delicate assemblies profit from the pin’s low bending tendency and consistent contact geometry. The clear numeric tolerance offers an immediate decision basis for acceptance or rework, supporting lean inspection routines.

Robust workshop construction for everyday use

Built as a workshop‑grade instrument, the pin is machined from special steel for wear resistance and dimensional stability under repeated use. The 50 mm working length balances insertion depth and handling comfort, while the compact mass (approx. 0.15 kg) makes placement and removal straightforward during batch sampling. Delivered in a dedicated transport case, the pin is protected in transit and storage — a practical detail that preserves calibration and surface condition between inspections. The construction emphasises durability without sacrificing the fine runout and concentricity required for reliable plug‑type gauging.

Fits into established inspection workflows and tooling

The gauge pin integrates seamlessly with existing fixtures, plug gauges and comparator setups, supporting repeatable checks at incoming inspection, in‑process control and final verification. Traceable identification (SKU M323.I91, GTIN available) simplifies inventory and quality records, while the precise nominal diameter reduces measurement uncertainty when used as a reference artefact. For production environments seeking to lower scrap rates and speed go/no‑go decisions, the pin acts as a simple, dependable standard that streamlines routine metrology tasks and improves throughput.
