Gauge pin M323.C77 — Ø 12.77 mm, 50 mm length, Metav IndustryLine

The Gauge pin M323.C77 is a single, precision inspection pin for micro‑range gauging and end‑measurement tasks in workshop environments.

• Precision tolerance ±0.002 mm
• Workshop‑grade special steel construction
• Supplied in protective transport case

Repeatable measurements for fine tolerances

Precision in repeated checks reduces reject rates and shortens inspection loops. The pin’s tolerance of ±0.002 mm and Ø 12.77 mm diameter make it suitable for high‑repeatability reference and limit checks where microscopic deviations matter. Used as a fixed reference in fixture inspection or as a go/no‑go master for seating and bore checks, the compact geometry minimises leverage and bending moments, supporting consistent results across many cycles. The result is fewer reworks and a smoother production flow when small clearances decide part acceptance.

Robust design for everyday workshop use

A workshop version built from special steel gives practical resistance to handling and repeated seating into bores. At 50 mm length the pin balances reach and rigidity, so it is easy to manage in handheld or fixture applications without excessive deflection. The solid construction and modest mass contribute to stable handling during quick checks, and the delivery in a protective transport case preserves the measuring surface during storage and transit, maintaining reference quality between uses.

Suited to micro‑range inspection and fine mechanics

Classified in the micro range for measuring tasks up to 100 mm, this single gauge pin is particularly useful in toolrooms, watchmaking, small gearbox subassemblies and precision jigs. The compact format supports access to confined geometries and inner seats where larger gauges cannot reach. Traceability is supported by the clear item identification: the SKU M323.C77 and GTIN ensure simple inventory integration and unambiguous part control in quality documentation.

Practical benefits for quality workflows

Integrating a small, accurate reference pin into inspection routines speeds decision making at the control station and simplifies fixture set‑up checks. The combination of workshop robustness and fine tolerance enables reliable in‑process checks that protect downstream assembly and reduce overall inspection time. For firms aiming to standardise quick acceptance tests without complex measurement rigs, this compact pin is a pragmatic component of a lean metrology toolkit.
