M323.421 Gauge Pin – 4.21 mm, ±0.001 mm, 50 mm Length (Metav IndustryLine)

The M323.421 gauge pin is a high‑precision end‑measurement pin designed for repeatable dimensional checks and Go/no‑Go verification in workshop metrology.

• Diameter guaranteed at 4.21 mm ±0.001 mm
• Ground from special steel for wear resistance
• 50 mm length for end-measure inspection
• Workshop version for routine dimensional checks

Precision where it matters: consistent measurement with micron accuracy

This precision pin delivers a diameter of 4.21 mm with a narrow tolerance of ±0.001 mm, ensuring measurements that are both repeatable and traceable in routine inspection workflows. The tight tolerance reduces uncertainty when verifying bores, shafts or calibration standards, which translates into fewer rejected parts and more reliable process control. The compact design keeps handling straightforward while delivering laboratory‑grade accuracy for shop‑floor use.

Built for longevity: material and finish that resist wear

Manufactured from special steel and ground to finished size, the pin offers elevated wear resistance and dimensional stability under frequent use. The hardened and ground surface reduces fretting and abrasion during repeated insertion into bores and pin blocks, extending service life and maintaining measurement integrity. For quality assurance routines, a durable gauge pin minimises the need for frequent replacement and preserves measurement consistency over time.

Practical inspection benefits: fit, form and function simplified

At a length of 50 mm, the pin is optimised for end‑measure and go/no‑go applications where full insertion depth is required. Its geometry eases handling during manual checks and pairs well with pin holders or simple fixtures for comparative gauging. The product supports efficient inspection cycles by combining a familiar, single‑piece format with the precise dimensional control expected in machine shops and inspection benches.

Integration and procurement advantages for industry buyers

As part of the Metav IndustryLine, the pin suits standard workshop environments and complements pin sets or bespoke test rigs. Clear labelling and a stable specification make procurement and inventory management straightforward. The compact mass and uncomplicated format permit easy storage and rapid retrieval for batch checks, while the proven specification assists in harmonising measurement routines across multiple workstations.
