Test pin, single, 19.78 mm, length 50 mm — Gauge pin Ø 19.78 mm, 50 mm length (Metav IndustryLine)

A test pin for precision end‑measurements and reference gauging in industrial metrology, designed as a workshop‑grade pin for fixture setting and bore verification.

• Workshop‑grade special steel
• Diameter 19.78 mm ±0.002 mm
• Length 50 mm for compact fixtures

High‑precision measurements with reliable repeatability

The fine tolerance of ±0.002 mm places this gauge pin in the category for demanding inspection tasks where dimensional certainty is essential. Manufactured from special steel, the pin maintains its form under repeated use, reducing wear‑related drift and preserving the original diameter for consistent readings. As a hardened reference shaft, the component is suited to datum checks, plug gauging and positional verification in inspection routines, producing reproducible results that accelerate quality control processes.

Compact design that simplifies fixture integration

With a length of 50 mm and a nominal diameter of 19.78 mm, this single test pin is optimised for tight fixtures and confined bores. The compact profile eases handling in assembly and fixturing operations while ensuring sufficient engagement for accurate end‑face and bore assessments. The small footprint supports ergonomic mounting in gauge blocks and inspection rigs, improving throughput where space and access are limited without compromising measurement fidelity.

Material and surface finish explained for non‑specialists

The pin is made from special steel, a designation indicating a purpose‑chosen alloy and heat treatment aimed at wear resistance and dimensional stability. In practical terms, that means longer service life and fewer replacements compared with untreated shafts. Surface finish and hardness are controlled to minimise friction and local deformation at contact points; consequently, measurement scatter is reduced and calibration intervals can be extended in routine environments.

Practical applications and process advantages

This gauge pin is ideal for end‑measurement tasks such as quick bore checks, setting reference depths and verifying component seats during assembly. When used as a reference element in modular gauges, the pin’s tight tolerance reduces uncertainty in pass/fail decisions and supports faster inspection cycles. The design suits workshops, toolrooms and production control stations where efficient, repeatable checks feed back into process stability and fewer downstream rejects.
