A D pin with R clip for scaffolding, also known as a hitch pin or truss pin, is a high-strength fastening component used in scaffolding and modular structural systems. Made from heat-treated boron steel and secured with an R-clip, this pin ensures fast locking, secure alignment, and reliable performance on construction sites.
Instead of using threaded fasteners, contractors rely on this pin-and-clip mechanism for faster assembly. As a result, erection time reduces significantly, especially in high-rise, industrial, and infrastructure projects.

D Pin with R Clip Size & Compatibility
D pin with R clip sizes vary depending on system requirements and load conditions. These pins are designed to fit standard cuplock verticals, truss frames, and modular scaffolding joints.
Because of their standardized dimensions, contractors can easily source replacement pins without compatibility issues, ensuring uninterrupted workflow on-site.
Applications of Hitch Pin in Scaffolding
Contractors use D pins with R clips across multiple applications:
-
Connecting scaffolding frames and vertical standards
-
Maintaining alignment during erection
-
Ensuring secure load transfer between members
-
Quick assembly in high-rise and infrastructure projects
-
Temporary structures, stages, and truss systems
Where and Why the D Pin Is Used
In modular scaffolding and truss systems, speed and safety matter. That’s why the Hitch pin becomes essential.
Its bullet-style design allows quick insertion, while the R-clip prevents accidental loosening during vibration or load movement. Consequently, the connection stays secure even during repeated use.
Moreover, heat-treated boron steel construction delivers high shear strength. As a result, these pins perform reliably under heavy loads in construction, events, and industrial structures.
