Precision U Head Jack Base with Solid Adjustable Screw Plate
Our steel scaffolding screw jacks (threaded jacks) are the core adjusting components of the system. They are mainly divided into U-shaped jacks for the top and bottom jacks. Depending on the structure and materials, the products cover various types such as solid screws and hollow screws, as well as common types and types with movable casters. They can meet the different needs of engineering support and moving scaffolding. We accept customization according to customer drawings. We provide high flexibility in terms of size, surface treatment, and component forms (such as individual screws or nuts), ensuring that the appearance and performance of the products meet the requirements.

Advantages
All-category solution, precisely matching requirements
We offer a complete range of screw jacks, including top supports (U-heads), bases, solid and hollow screws, with options for wheels or rotating bases in various models. No matter which structure you need (fully welded or split type with screw and nut), we can customize according to the drawings to ensure that the product is completely consistent with your design.
The materials and craftsmanship are flexible to choose, balancing performance and durability.
The product offers two types of screw materials: solid round steel and hollow steel pipe. It also provides various surface treatment processes such as painting, electroplating, hot-dip galvanizing, and raw black material. The hot-dip galvanized wheel base is specially designed for mobile scaffolding, providing rust prevention and facilitating transportation; the standard model ensures stable support and fully meets the strength and anti-corrosion requirements of engineering scenarios.
Deep customization capabilities and ODM support
We are not just manufacturers; we are also your collaborative R&D partners. We can precisely manufacture various special-shaped bases and screw structures based on customer drawings, achieving 100% restoration of appearance and function. The split design (screw and nut produced separately) is more convenient for on-site replacement and maintenance, providing highly flexible assembly solutions.
