Gauge pin M323.I78 — 18.78 mm diameter, 50 mm length (Metav IndustryLine)

The gauge pin M323.I78 is a single precision test pin designed for end‑measurement and fit inspections in workshop and production metrology, particularly for quick go/no‑go checks and dimensional verification of machined components

• Workshop specification
• 18.78 mm nominal diameter
• Tolerance ±0.002 mm
• Delivered in transport case

Precision for repeatable end measurements

The pin provides a measurable improvement in process reliability because the nominal 18.78 mm diameter and the specified ±0.002 mm tolerance translate directly into tighter acceptance criteria during incoming inspection or in‑process checks. Manufactured from special steel, the geometry and surface finish reduce seating errors and measurement scatter; this results in fewer false rejects and a clearer statistical basis for quality decisions. For end‑measurement tasks and fit checks, the combination of 50 mm usable length and compact mass supports steady hand positioning while remaining compatible with common jigs and fixture designs. The clearly defined tolerance allows engineers to integrate the pin into control plans and SPC routines with confidence in repeatability.

Built for workshop handling and longevity

The workshop execution emphasises practical durability: the selected special steel balances hardness and resistance to surface damage, while a careful finish preserves the effective diameter over repeated use. Supplied in a protective transport case, the test pin is ready for secure storage and damage‑free transport between inspection benches or job sites. Robust construction minimises maintenance intervals and reduces the need for frequent replacement, supporting lean inventory practices and uninterrupted production cycles. The modest mass and compact form provide ease of handling during high‑throughput checks, helping to maintain steady cycle times without compromising accuracy.

Integrating the pin into inspection workflows

As a compact dimensional standard, the pin suits simple plug‑gauge routines, bench checks and reference stack assemblies. It functions well for verifying bores, locating features and checking mating fits in assemblies; the repeatability of the geometry simplifies acceptance criteria in work instructions. When included as a reference artefact in a fixture, the pin supports reproducible positioning and faster changeover, translating precision into operational efficiency. For users seeking traceable calibration or specific reporting, Metav IndustryLine can advise on calibration pathways and documentation to match internal quality systems and audit requirements.
