Spigot pin (or joint pin) are essential components in scaffolding, used to securely connect two vertical tubes. By creating a strong, rigid joint, they help the scaffold withstand both lateral and vertical loads. Made of durable steel, joint pins provide the necessary strength and stability.

They also allow for height adjustments by joining vertical sections, making it easier to adapt the scaffold to various structures. Proper use of joint pins and adherence to safety guidelines are crucial to prevent accidents and ensure safe scaffolding construction.
