Screw jack base

Our Screw Jack Base is an essential adjustable support component used in scaffolding systems to provide accurate leveling and stable load transfer between the scaffold structure and the ground. It allows height adjustment to compensate for uneven surfaces, ensuring safety and structural stability during construction.

Screw jack bases are widely used with Frame Scaffolding, Ringlock, Cuplock, Kwikstage, and other system scaffolding.

Applications

Used for frame scaffolding system, our screw jack bases are made from high quality steel, with galvanized.  Solid screw jack rod is welded to a 5"x5" base plate.

Heavy duty capacity, adjustable working height, perfect for your scaffolding system, including 1'5/8" and 1-11/16" walk thru frame scaffolding, ladder frame scaffolding, etc.
The Nut on the Screw Stem is High-Strength, Forged Steel for durability Acme Threads are used on the Screw Stem. 
There is a Notch/Cut in the threads of the Screw Stem, 6" from the top, to prevent the Nut from coming off, and to keep the Screw Jack from being over-extended. 

Key Features of Screw Jack Base

Adjustable Height for Precise Leveling

The threaded rod design allows easy height adjustment, making screw jack bases ideal for uneven ground or sloped surfaces.

High Load-Bearing Capacity

Manufactured from high-strength steel, screw jack bases are designed to support heavy vertical loads in construction and industrial applications.

Strong and Stable Base Plate

The welded steel base plate ensures stable contact with the ground or sole board, improving overall scaffold stability.

Durable Surface Finish

Available with painted, electro-galvanized, or hot-dip galvanized finishes, providing corrosion resistance and extended service life.

Main Components of a Screw Jack Base

A standard screw jack base consists of:

▪ Threaded Solid or Hollow Rod

▪ Steel Base Plate

▪ Adjustment Nut

▪ Locking Collar (optional)

Each component is precision-manufactured to ensure smooth adjustment and reliable load performance.

Types of Screw Jack Base

• Solid Screw Jack Base

Made from solid steel bar, offering higher load capacity, suitable for heavy-duty scaffolding applications.

• Hollow Screw Jack Base

Manufactured from steel tube, providing a lighter-weight and cost-effective solution for standard construction projects.

• Adjustable Screw Jack with U-Head (Jack Head)

Used for shoring systems and formwork support, especially in slab and beam construction.
