What Is a Spigot Pin in Cuplock Scaffolding Systems?
A spigot pin for cuplock scaffolding connects two vertical scaffold tubes in a straight line, ensuring proper alignment and secure load transfer. It fits inside standard 48.3mm scaffold pipes and plays a critical role in maintaining structural stability in multi-level scaffolding systems. This spigot pin for cuplock scaffolding ensures strong vertical connections with accurate fit, reducing movement and improving site safety.
In cuplock scaffolding, the spigot pin prevents misalignment between stacked standards and supports safe load distribution. Because the pin fits inside the tube, it creates a clean and secure internal connection without increasing the external diameter.
The standard 38mm spigot pin fits precisely inside 48.3mm OD scaffold tubes. AMCO Exports manufactures these joint pins with tight dimensional tolerance to ensure consistent performance, reduced movement, and improved site safety.
👉 This design ensures faster installation, better alignment, and reliable performance on construction sites.
This spigot pin works seamlessly with scaffolding couplers, cuplock scaffolding system components, and formwork accessories like tie rods and wing nuts to provide complete structural support.

Hot Dip Galvanized Spigot Pin with 100 Micron Zinc Coating
To ensure long-term durability in outdoor and heavy-duty construction environments, AMCO spigot pins are available in Hot Dip Galvanized (HDG) finish.
The galvanization process coats the steel with a thick layer of zinc, protecting it from rust, corrosion, and weather exposure.
✔ Zinc Coating Thickness: Up to 100 microns
✔ Uniform coating inside and outside surface
✔ Suitable for coastal, high-moisture, and industrial sites
✔ Significantly longer life compared to painted or zinc-plated finish
This makes HDG spigot pins ideal for infrastructure projects, bridges, industrial plants, and long-duration scaffolding use.
Zinc Coating Thickness (Micron Test & Quality Check)
Every batch of galvanized spigot pins undergoes coating thickness testing (micron test) to ensure consistent quality and compliance with industry standards.
✔ Tested using digital coating thickness gauge
✔ Ensures uniform zinc layer across surface
✔ Prevents early corrosion or coating failure
✔ Maintains durability under load and weather exposure
Typical coating range: 80–100 microns (as per project requirement)
👉 This ensures you get verified quality, not just claimed coating
