Gauge pin M323.E31 — 14.31 mm diameter, 50 mm length (Metav IndustryLine)

Gauge pin M323.E31 is a single precision test pin designed for end-size checks, fixture alignment and repeatable hole gauging in workshop environments.

• Workshop-grade construction
• Diameter 14.31 mm precision
• Length 50 mm hardened special steel
• Tolerance ±0.002 mm

Reliable checks for end-size and assembly alignment

This precision test pin delivers repeatable end-size verification thanks to its ±0.002 mm tolerance and ground finish. Where consistent hole gauges or alignment pins are required, the component's geometry reduces measurement scatter and speeds up inspection loops, improving throughput and lowering rework rates. The combination of tight dimensional control and robust surface finish makes this pin suitable for routine process checks and final assembly verification, providing an immediate quality-control advantage on the production line.

Designed for workshop durability and handling

Manufactured in special steel and offered in a workshop specification, the pin resists wear during frequent use and maintains roundness and length stability under normal handling. The 50 mm overall length affords secure gripping during manual gauging while keeping the test point accessible in fixtures. These mechanical characteristics reduce the need for frequent replacements and contribute to lower lifecycle costs, making the component an economical choice for busy shops that require both durability and easy handling.

Practical benefits for inspection and jigs

As a single precision pin, this item integrates simply into existing gauge sets and jigs. The plain cylindrical form ensures straightforward use for pass/no‑go checks, alignment aids and as reference dowels in assembly fixtures. Clear labelling and a unique SKU make inventory management easier in busy stores, while the compact mass supports fast changeover during inspection tasks — a practical step towards leaner measurement routines and fewer bottlenecks.

Traceability and suitability for everyday workshop use

The construction and measured tolerance make the pin well suited to repetitive checks in production and maintenance contexts. Its form factor supports consistent seating in bores and sleeves, which helps to standardise measurement procedures across shifts and operators. When paired with calibrated reference gauges, the pin assists in establishing reliable in‑process control points that feed into documented quality records.
