Gauge pin, single — Ø 4.44 mm, ±0.001 mm tolerance (50 mm length) by Metav IndustryLine

The gauge pin is a workshop-grade precision pin for end-dimension checks and alignment tasks, designed for repeatable measurements in production and inspection environments.

• Gauge pin Ø 4.44 mm, tolerance ±0.001 mm
• 50 mm workshop-length steel pin
• Delivered in protective transport case
• High repeatability for end-dimension checks

Reliable accuracy that keeps production moving

Built for repeatable checks in busy workshops, this precision pin provides a diameter of 4.44 mm with a tolerance of ±0.001 mm, ensuring consistent fit assessment and go/no-go verification. The very small tolerance reduces measurement uncertainty when checking mating parts, bores or finishing operations, which in turn helps to prevent rework and assembly issues. The compact 50 mm length offers a balance between handling convenience and sufficient engagement for end-dimension control, making it suitable for bench testing and inline inspections.

Robust material and workshop-ready design

Manufactured from special steel, the pin resists wear from frequent contact and retains dimensional stability under typical workshop handling. The workshop execution provides a practical finish that tolerates everyday use while maintaining the required measurement integrity. A protective transport case is supplied for secure storage and safe transit between workstations, reducing the risk of accidental damage and preserving the pin’s calibrated fit over time.

Practical integration into inspection workflows

The pin is optimised for end-dimension verification, alignment checks and fixture set-up. Thanks to its narrow tolerance band and stable construction, it functions well as a reference plug in repetitive quality-control routines. Where traceable calibration is required, Metav Werkzeuge can advise on compatible calibration services to fit existing QA procedures; the pin’s specification supports straightforward documentation in inspection reports and measuring logs.
