Gauge pin M323.398 — single precision test pin, Ø 3.98 mm, ±0.001 mm, 50 mm

The Gauge pin M323.398 is a single precision test pin designed for end‑measure checks and reference gauging in workshop metrology, providing a compact, repeatable datum for go/no‑go and comparative measurements.

• Workshop‑grade design for daily use
• Diameter 3.98 mm, ground to size
• Tolerance ±0.001 mm for precise gauging
• Length 50 mm, stable reference length

Accurate measurement that improves process control

The pin offers ±0.001 mm tolerance, which places it at the high end of workshop gauging and supports repeatable, verifiable checks on critical features. As a hardened test element with a nominal diameter of 3.98 mm, the component serves as a fixed reference when verifying bore seats, locating holes or validating end‑measure dimensions. The tight tolerance reduces measurement scatter and helps to identify machining deviations earlier, improving first‑pass yield and reducing rework.

Robust design for everyday workshop use

Manufactured in special steel and presented in a workshop version, the pin is built to withstand routine handling and frequent seating in fixtures. The 50 mm length provides a stable datum without excessive overhang, so measurements remain reproducible across a run of parts. The construction balances stiffness and handling convenience, making the pin suitable for inspection benches, fixture setups and manual gauging workflows where a reliable reference is required under repeated use.

Practical handling and integration into workflows

The test element is simple to incorporate into existing gauging jigs or hand‑held checks. Its nominal 3.98 mm size and defined reference length mean it can be used as a plug gauge, spacer or alignment pin in assembly checks and tool setup. Routine maintenance consists of keeping the contact surfaces clean and free from burrs; periodic visual inspection and, where required by quality plans, comparison against a calibrated master will preserve the reference capability and long‑term repeatability.
