Gauge pin M323.251 — Metav IndustryLine test pin, Ø 2.51 mm, ±0.001 mm

A gauge pin M323.251 designed for precise end‑measure checks and fit testing in workshop and inspection environments

• Ultra‑fine tolerance ±0.001 mm
• Diameter 2.51 mm for tight fits
• 50 mm length, workshop grade
• Hardened special steel construction

Consistent pass/fail assessment with micrometre‑level tolerance

This workshop‑grade pin is made for repeatable verification tasks where precision matters. The ±0.001 mm tolerance reduces uncertainty in fit and end‑measure checks, turning subjective gauging into objective data. Thanks to the 2.51 mm diameter and the straight, ground shaft, the pin seats reliably in bores and gauges, so measurement chains and go/no‑go workflows remain consistent over many cycles. The design supports quick interchange in fixtures and simplifies regular inspection routines.

Robust design for everyday metrology use

Constructed from special steel and finished for durability, the pin copes with frequent handling in production and workshop environments. The 50 mm length gives sufficient engagement for stable positioning while staying compact for tight setups. The material choice delivers wear resistance and dimensional stability, which translates to fewer replacements and lower downtime. Where rough handling and repeated seating are common, the hardened shaft preserves the calibrated geometry for longer service life.

Practical handling and transport for the workshop

Delivered in a protective plastic or wooden transport box, the pin arrives ready for safe storage and on‑the‑bench use. The compact packaging protects the ground surface and the tip geometry during transit and prevents accidental damage in tool drawers. Lightweight at approximately 5 g, the component integrates easily into gauge sets and trays without adding bulk, which keeps tool control and workplace organisation efficient.

Integration into inspection routines and traceability

Although compact, the pin suits standardised inspection procedures and can be included in master sets or calibration schedules. The exact diameter and tolerance support traceable checks and documented acceptance criteria in go/no‑go testing. For traceability and inventory management, the article is identified by its SKU and GTIN, making procurement and record‑keeping straightforward for quality departments and stores.
