Gauge pin M323.178 — 1.78 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Gauge pin M323.178 is a workshop‑grade inspection pin designed for precise end‑measurements, fit checks and alignment tasks in assembly and quality control environments.

• Diameter 1.78 mm, tolerance ±0.001 mm
• Length 50 mm for deep bores
• Special‑steel construction
• Delivered in protective case

Reduce rework with micrometric repeatability

The exceptionally tight ±0.001 mm tolerance (1 µm) of this inspection pin ensures measurable reductions in dimensional uncertainty during routine checks. Accuracy at this level converts directly into fewer rejected parts and less rework, because a reliably calibrated reference pin gives a clear go/no‑go condition for small bore diameters. The compact diameter is ideal where space is limited yet precision remains essential; the hardened shaft maintains roundness under repeated insertion, supporting consistent results across inspection cycles. Bold, verifiable tolerances make specification and documentation straightforward for quality records.

Built for workshop handling and durability

Constructed from special steel, this workshop‑grade test pin balances wear resistance with the dimensionally stable finish necessary for repeated gauging. The 50 mm shank provides sufficient engagement in moderate‑depth bores while keeping the tool easy to manoeuvre by hand or with light fixtures. Supplied in a protective case, the pin is protected from transport damage and contamination, preserving the measuring surface and minimising downtime for cleaning or dressing. The simple geometry of the pin also facilitates fast visual inspection for wear before use, helping to maintain inspection integrity over time.

Practical use in inspection and assembly workflows

This small‑diameter gauge is intended for end‑measurement, alignment verification and fit checks in component assembly and precision cleaning processes. The smooth, calibrated shaft functions as a reliable reference for gauging internal diameters, for locating features during assembly and for checking concentricity in small parts. Lightweight and compact, the pin integrates easily into quality control benches and fixture setups; traceable identification (SKU M323.178) simplifies inventory and audit processes. For operations that prioritise stable short‑range measurements, this inspection pin provides a pragmatic balance of precision and handling efficiency.
