- Scaffolding Coupling Joint Pin Photos
Wellmade’s Scaffolding Coupling Pins are customized sizes according to the inner diameter of the scaffolding frame verticals, scaffolding pipe, and system scaffold poles internal dimensions.
Scaffolding Coupling Pins
Scaffolding coupling pins are spigot joint pins of the scaffolding. They are inserted into scaffold legs during construction, stacking the scaffolding to the required height.
There are many types of scaffolding coupling pins, simple straight couplings, coupling pins with washers, coupling pins with collars, etc.
The scaffolding coupling joint pin diameter is smaller than the scaffold legs and matches the inner diameter of the scaffold legs.
In construction, the scaffolding coupling pins are secured by the scaffold pitails, clevis pins with split cotter pins, bolts and nuts, D pins, and span pins.

How to Fix the Scaffold Coupling Pin On Scaffold Tube
In construction, scaffold coupling pins are inserted into the ends of scaffold tubes. To tighten the scaffold spigot on the scaffold tubes and poles, bolt and nut, or scaffolding clips are used to fix them well by holes on the coupling spigot.
The fixing scaffolding clips could be toggle pins, pigtails, gravity pins, spring clips, roll pins, cotter pins, span pins, etc. Bolts and nuts are used for center tightening of the scaffold spigot pins for ringlock, cuplock vertical products.
