Heavy Duty Adjustable Base Jack for Hollow & U-Head Support

Short Description:

Screw jacks serve as indispensable core components across diverse scaffolding systems, primarily functioning as height-adjustment fittings for scaffold assemblies. These items fall into two core categories: base jacks and U-head jacks, among which the Hollow Jack Base stands as a popular variant of base jack solutions. Multiple surface finishing options are available to meet varied anti-corrosion needs, including paint coating, electro-galvanizing and hot-dip galvanizing.

We customize critical specifications such as base plate structure, nut styles, screw profiles and U-head plate dimensions in line with clients’ bespoke demands. Such flexible customization results in a wide array of screw jack configurations with distinct appearances. We’re capable of developing tailor-made screw jack products strictly per your specific project requirements

1. Custom Engineering & Precise Matching
We manufacture a full range of screw jacks—including hollow, solid, swivel, and caster-wheel types—strictly according to customer drawings. Our products achieve nearly 100% visual consistency with your samples, earning consistent high praise for accuracy.

2. Flexible Material & Load Options
Choose between hollow screw jacks (made from steel pipe, ideal for lighter weight) and solid screw jacks (made from round steel bar, for heavy-duty support). This allows you to match the exact strength and weight requirements of your scaffolding system.

3. Versatile Surface Treatment & Partial Components
Surface finishes include painted, electro-galvanized, hot-dip galvanized, or black—suitable for different durability and corrosion resistance needs. Additionally, if welding is not required, we can supply only the threaded screw and nut separately, giving you greater assembly flexibility.
