Gauge pin, single, 12.55 mm, 50 mm length — workshop‑grade reference pin (Metav IndustryLine)

The Gauge pin, single, 12.55 mm, 50 mm length is a workshop execution reference pin intended for precise end‑gauging, alignment checks and fixture setup in production and inspection environments.

• Workshop execution
• Diameter 12.55 mm for tight fits
• Accuracy ±0.002 mm
• Solid special‑steel construction

Precision that reduces rework and speeds inspection

A compact reference pin with a 12.55 mm working diameter delivers measurable gains in inspection throughput by providing a stable datum for end‑measurements. The manufactured tolerance of ±0.002 mm ensures consistent repeatability across multiple checks, supporting reliable go/no‑go decisions in first‑article inspection and small‑batch production. As a micro‑range instrument, this pin is tailored to applications where limited envelope space and high local stiffness are required, avoiding the handling variability inherent in longer probes.

Built for everyday workshop use

Manufactured from special steel, the reference pin combines wear resistance with a geometrically stable shaft, resulting in long service life under normal contact conditions. The 50 mm length balances reach and rigidity: short enough to remain torsion‑resistant in hand‑held checks, yet long enough to engage located bores and alignment points in jigs and fixtures. The workshop execution emphasises robust finishing and handling features that reduce the risk of damage during routine use.

Integrating the pin into measurement workflows

The test pin functions as a fixed datum in fixture checks, alignment verification and reference measurements for small components. Due to its compact form factor it is well suited for repeatable positioning in assembly aids and dimensional gauges. When incorporated into routine inspection routines, the pin helps to shorten set‑up times and improves comparability between measurement runs. For traceability, record the SKU and GTIN when logging inspection artefacts and ensure consistent placement in gauges and carriers.

Practical advice for handling and applications

Treat the pin as a precision reference: store it in a clean, dry environment and avoid knocks against hard surfaces to preserve the specified tolerance. The pin’s mass and finishing support easy manual handling during sample checks and bench inspections. Typical applications include plug checks for bores, alignment points in assembly jigs and use as a master for comparative measurement tasks where a reliable contact surface is required.

FAQ

What tolerance can be expected from this gauge pin?
The gauge pin (12.55 mm × 50 mm, SKU M323.C55) is produced to a manufacturing tolerance of ±0.002 mm, providing the repeatability needed for precise end‑gauging and alignment checks.

Is the pin suitable for small‑bore inspection and precision fixtures?
Yes, the compact form and 12.55 mm diameter make this reference pin ideal for micro‑range inspection tasks and use in assembly or inspection fixtures where space and stiffness are constraints.

What material is the pin made from and why does it matter?
The pin is made from special steel, chosen for its wear resistance and dimensional stability; this material keeps the contact surface durable and the reference geometry consistent over repeated use.

How should the gauge pin be stored to maintain accuracy?
Store the pin clean and dry in a protective environment to avoid corrosion and mechanical damage; routine visual inspection before use helps to ensure the contact surface remains free from nicks or contamination.

Can the pin be used as a master for comparative measurements?
Yes, the reference pin serves well as a master in comparative checks and setup tasks, where its consistent diameter and high repeatability reduce measurement uncertainty.
