D pin

The D Pin, also known as a truss pin or bullet pin, is a high-strength fastening component made from heat-treated boron steel. Cold forged for superior durability and finished with zinc plating, this essential pin is secured with an R-clip for reliable performance in scaffolding and structural applications.

Key Specifications:

  • Material: Boron Steel

  • Manufacturing Process: Cold Forged and Heat Treated for superior strength

  • Finish: Zinc Plated for corrosion resistance

  • Accessory: Secured with R-Clip for added safety

  • Also Known As: Truss Pin / Bullet Pin

D Pin

A D Pin is a small but essential connector used in cuplock scaffolding systems to secure and align vertical standards. Its simple locking design makes assembly fast, stable, and safe, especially on high-load construction projects. Contractors rely on it because it delivers a tight, consistent fit without the need for additional tools.

Key Features 

  • Heavy-duty forged steel for long service life

  • Accurate locking shape ensures secure alignment between standards

  • Corrosion-protected finish for harsh site conditions

  • Fast to insert and remove, improving project speed

  • Universal fit for most cuplock vertical members

Applications in Cuplock Scaffolding

  • Connecting vertical standards

  • Maintaining alignment during erection

  • Ensuring stable load transfer

  • Quick joining during high-rise, industrial, or infrastructure scaffolding setup

Where And Why It Is Used

The D Pin is a critical component in modular scaffolding systems, particularly for connecting truss sections and structural frames.

Its bullet-shaped design allows for easy insertion and secure locking with an R-clip, making it ideal for rapid assembly and disassembly of scaffolding,

temporary stages, and event structures. The use of boron steel and heat treatment ensures exceptional shear strength and durability under heavy loads.

FAQ

Q1: What is a D Pin used for in scaffolding?

A1: The D Pin, also called a truss pin or bullet pin, is used to securely connect modular scaffolding and truss systems, with the R-clip ensuring it stays locked in place.

Q2: Why is boron steel used for these pins?

A2: Boron steel provides superior strength and durability. Combined with cold forging and heat treatment, it creates an exceptionally strong truss pin capable of handling heavy structural loads.

Q3: How does the R-clip work with the D Pin?

A3: The R-clip slides through a hole in the D Pin once it is inserted, preventing it from accidentally working loose and ensuring a secure connection.

Q4: What are the advantages of a bullet pin design?

A4: The bullet pin design allows for quick and easy insertion and removal, speeding up the assembly and dismantling of scaffolding and temporary structures.

Q5: Are you direct manufacturers of these pins?

A5: Yes, as a premier Scaffolding Pin & Tool Manufacturer and Lock Pin Exporter from India, we produce high-quality D Pins for the global market.
