R Pin / Connecting Pin for Cuplock Scaffolding
The R Pin (Connecting Pin) is an essential locking fastener used in Cuplock scaffolding systems, designed to keep vertical standards securely connected during construction work. When used with a Spigot Pin, the R Pin holds the joint in place, preventing any vertical movement or accidental disconnection while the scaffolding is under load. Its role may look small, but it directly contributes to the overall safety and stability of the structure.
Manufactured from Grade 8.8 boron steel, the R Pin is heat-treated to achieve high tensile strength, making it suitable for harsh site conditions. The 16 × 100 mm size fits standard Cuplock verticals and spigots, ensuring universal compatibility across construction and industrial scaffolding systems. With an electro-zinc plated finish, the pin resists rust and moisture, maintaining strong performance even during long-term exposure to outdoor conditions.
Using an R Pin is simple: insert the spigot pin into the vertical standard, align the holes, and slide the R Pin into place. The curved “R” shape locks automatically, ensuring a secure connection without the need for tools. This quick, tool-free installation makes it highly efficient on fast-moving projects where speed and safety are critical.
Beyond construction, R Pins are used in industrial maintenance, infrastructure works, and high-rise shuttering setups. Their reusability makes them a cost-effective option for contractors and rental companies. With packing options of 125 pcs/bag and 7000 pcs/pallet, they are supplied ready for bulk use and export demands.
Whether you’re assembling tall scaffolding towers or creating stable working platforms, the R Pin Connecting Pin ensures every vertical joint remains secure, aligned, and safe throughout the project.
