Gauge pin M323.442 — Single 4.42 mm, ±0.001 mm, 50 mm (Metav IndustryLine)

A gauge pin designed for precision end‑measurements and inspection tasks in workshop and production environments.

• ±0.001 mm manufacturing tolerance
• Nominal diameter 4.42 mm
• 50 mm hardened rod length
• Workshop‑grade finish

Precise results where it matters

This single test pin delivers a ±0.001 mm tolerance, enabling highly repeatable go/no‑go checks and reference measurements for small bores and locating holes. The compact 50 mm length and nominal 4.42 mm diameter make it suitable for tight spaces where exact end‑measurements are required. By specifying a fine tolerance rather than a broad range, the component reduces uncertainty in quality control routines and shortens inspection time, which supports lean production and fewer reworks.

Robust construction for everyday workshop use

Manufactured from special steel, the pin is produced as a workshop‑grade component that withstands frequent handling and seating stresses typical in assembly and inspection jigs. The material choice balances wear resistance with dimensional stability, so measuring and gauging procedures retain accuracy over many cycles. The solid design also simplifies handling and storage compared with composite or plated alternatives, supporting durable, long‑term use on the shop floor.

Practical efficiency and integration into workflows

As a single gauge pin, this item is straightforward to integrate into existing inspection routines: it functions as a reference mandrel for bore checks, a go/no‑go element in fixtures, or a locating pin for assembly set‑ups. Clear nominal data and tight tolerance aid calibration planning and traceability, reducing the administrative overhead associated with ambiguous fitment specifications. The concise geometry minimises clamping and seating variability, helping inspection teams achieve consistent measurements with fewer adjustments.

Suitable applications and limits

The pin serves in precision inspection, fixture construction and small‑component assembly where end‑measurement accuracy is essential. Given the specified tolerance and compact dimensions, it is best applied to small bores, fine‑tolerance locating features and laboratory feeler tasks rather than large‑scale alignment jobs. The straightforward geometry implies easy interchangeability with comparable gauge pins in toolrooms and metrology benches.
