Applications of Jack Nuts

The Scaffolding Jack Nut is the adjusting component in scaffolding screw jack assemblies, including the Adjustable Scaffolding Screw Base Jack and Adjustable U Head Jack. It sits on the threaded stem and supports the vertical load of the scaffold.

Whether you are repairing old equipment or manufacturing new jacks, our base jack nut is the ideal choice. It is commonly used in Ringlock, Cuplock, and Frame scaffolding systems to level the ground. Don't forget to check our Steel Planks and other Scaffolding System Parts for a complete system.

Production Process

From casting to threading, we control every step. The adjusting nut undergoes sand blasting and galvanizing to ensure long-term rust protection.

  • 🔥 Casting: High precision molds.

Q: Is it load bearing?

A: Yes, our cast iron nuts are designed to bear the full weight of the scaffolding structure.
