What Is a Spigot Pin Used for in Scaffolding?
A spigot pin (joint pin) is used to connect two vertical scaffold tubes in a straight line. It fits inside the hollow ends of 48.3mm scaffold pipes and ensures proper vertical alignment and secure load transfer in Cuplock and conventional scaffolding systems.
In Cuplock scaffolding, the spigot pin plays a critical structural role. It prevents misalignment between stacked standards and helps maintain overall stability, especially in high-load and multi-level scaffold structures. Because it sits inside the tube rather than outside, it provides a clean, secure connection without increasing external diameter.
AMCO Exports manufactures heavy-duty 38mm spigot pins with precise dimensional tolerance to ensure tight internal fitment inside standard 48.3mm OD scaffold tubes. This improves structural safety and reduces movement at vertical joints during site load conditions.
