M323.D21 gauge pin — 13.21 mm diameter, 50 mm length, special steel by Metav IndustryLine

The M323.D21 gauge pin is a single test pin designed for precise end-measure checks and fit testing in workshop and production environments; it serves as a compact, robust solution where reproducible diameters and dependable contact geometry are required.

• Workshop version for robust daily use
• Diameter 13.21 mm for end-measure verification
• Tolerance ±0.002 mm for high repeatability
• Delivered in a plastic or wooden transport box

Consistent fit checks with industrial repeatability

The M323.D21 is engineered as a gauge pin for routine dimensional verification where repeatability and simple handling matter. Its 13.21 mm nominal diameter and declared ±0.002 mm tolerance make it suitable for quick go/no-go or comparative checks on bores and holes, supporting quality control processes on the shop floor. Because the pin is crafted from special steel, it maintains geometry under typical workshop loads and resists wear better than generic steels, which keeps inspection results stable over many cycles.

Practical benefits for production and jig setup

Featuring a 50 mm overall length, the pin gives sufficient engagement for most fixture and bore checks without excess overhang, balancing reach and stiffness. The workshop specification emphasises durability and ease of use, reducing downtime for handling and cleaning between measurements. When used as part of an inspection routine, the plug-style pin simplifies go/no-go assessment and speeds up setup tasks, improving throughput while keeping measurement uncertainty low — a rational efficiency gain for repetitive quality procedures.

Material and handling considerations

Made from special steel, the pin offers a reliable contact surface for tactile and optical comparison methods. The hardened surface reduces the rate of dimensional drift caused by surface wear; however, regular inspection against a master gauge is recommended for critical applications. Delivered in a protective plastic or wooden transport box, the single pin is kept secure in transit and storage, reducing the risk of damage to the polished measuring face and maintaining the intended measuring performance for longer.
