U-Head Screw Jack

In commercial concrete construction, the accuracy of your slab depends entirely on the stability of the primary beams supporting it. While a solid base screw jack levels the scaffold at the ground, the U-Head screw jack sits at the absolute top of your vertical standards. Acting as a secure, adjustable cradle, this specialized screw jack holds H20 timber beams, steel walers, or aluminum stringers firmly in place. Without a precision-threaded U-Head screw jack, horizontal beams are prone to lateral shifting and deflection under the immense dynamic weight of wet concrete.

Comprehensive Size Matrix (Engineered for Exact Beam Integration)

Slab elevations and beam dimensions vary by project. To ensure your formwork remains completely level without exposing an unsafe length of thread on the screw jack, we manufacture a comprehensive matrix of exact-fit sizes, including two distinct U-plate configurations to match your specific beam widths:

Unmatched Engineering & Structural Advantages:

• Anti-Roll U-Shape Geometry: Engineered to secure heavy loads, every SRE U-Head screw jack features a precision-bent U-plate made from 5mm thick MS. This cradle design tightly grips the primary runner beam, entirely eliminating the risk of lateral beam roll or dislodgment during heavy concrete vibration.

• Precision-Machined 4TPI Threads: Slab leveling requires exact adjustments. The high-efficiency 4TPI (Threads Per Inch) pitch allows field crews to make rapid, micro-adjustments to the screw jack height while maintaining maximum thread-to-nut friction and load-bearing lock capacity.

• Zero-Wobble Tube Tolerances: Available in precise 32mm, 34mm, and 38mm outer diameters, the threaded stem of the screw jack is machined to slide perfectly into your vertical standard tubes, preventing sway at the highest point of the scaffold.

• Customizable Jack Nut Metallurgy: To match your specific site budgets and load limits, we supply every screw jack with either Forged Jack Nuts for extreme impact resistance and heavy-duty industrial shoring, or Casted Jack Nuts for reliable, cost-effective performance on standard commercial setups.

Step-by-Step Screw Jack Installation Efficiency (Designed for EPCs):

Time on site directly impacts your pouring schedule. The SRE U-Head Screw Jack is engineered for rapid deployment. Erection crews simply insert the threaded stem of the screw jack into the top of the vertical standard, drop the timber or steel beam directly into the U-plate, and rotate the heavy-duty nut to perfectly level the formwork deck. The self-cleaning thread geometry on the screw jack sheds concrete slurry and cement dust, ensuring smooth adjustments even after multiple pouring cycles.

📦 Bulk Procurement & Global Export Supply

SRE understands the intense logistical demands of utility-scale concrete contractors and large formwork rental fleets. Every Heavy-Duty MS U-Head Screw Jack undergoes rigorous batch testing for U-plate weld strength, thread accuracy, and load deflection before being prepared for transit. We offer highly competitive, tier-based wholesale pricing structures for major domestic EPC contractors, alongside robust, palletized packaging configurations engineered to deliver your screw jack orders globally with zero transit damage.
