Gauge pin M323.I21 — precision plug gauge, 18.21 mm, 50 mm length (Metav IndustryLine)

The Gauge pin M323.I21 is a workshop‑grade reference pin for accurate bore gauging, alignment and dimensional verification in production and inspection routines.

• High tolerance ±0.002 mm
• Manufactured from special steel
• 50 mm length for stable seating
• Supplied in a protective transport case

Consistent inspection results through tight tolerance control

The ±0.002 mm tolerance class places this reference pin in the high‑precision segment suitable for demanding workshop inspections. As a hardened, single‑piece gauge pin, it provides a stable datum for bore gauging and alignment tasks where repeatability is essential. The numerical specification allows straightforward integration into quality procedures and ensures comparability of measured parts; technicians and inspection staff benefit from fewer ambiguous results and a clearer pass/fail decision when using calibrated reference gauges.

Robust material choice for everyday workshop use

Construction from special steel gives the pin a balance of wear resistance and dimensional stability under regular handling. The workshop version design takes account of everyday mechanical stress: socketing and seating remain repeatable over many cycles, with a mass that contributes to steady engagement without being unnecessarily heavy. Where common stainless options are not specified, the material selection still supports durable performance for general industrial and toolroom tasks.

Practical handling that reduces downtime

At 50 mm overall length the pin reaches sufficient depth for most standard bores while remaining easy to position by hand or with simple clamping aids. The single‑piece supply format simplifies inventory management and traceability in inspection logs. Critical features such as the nominal diameter 18.21 mm and documented tolerance allow direct referencing in measurement plans and work instructions, reducing setup time and clarifying acceptance criteria during audits.

Packaging and workshop logistics aligned to real needs

Delivery includes a protective case for transport, which eases storage and prevents transit damage to precision surfaces. The workshop construction and supplied transport case support mobile inspection routines and reduce the risk of surface abrasion during handling. For procurement teams, the compact footprint of this component simplifies stocking alongside other precision tools without the need for elaborate storage solutions.
