Product Description
In commercial construction, the accuracy of a concrete slab depends entirely on the stability and leveling of the formwork beneath it. The scaffolding fork head sits at the very top of your vertical standards, acting as the secure cradle that holds H20 timber beams or steel stringers firmly in place. Without a precisely threaded and securely welded fork head, beams are prone to lateral shifting under the immense dynamic weight of wet concrete.
Engineered Threading for Maximum Adjustment
Site engineers calculate shoring heights down to the millimeter. To accommodate diverse slab elevations, we manufacture these components with a highly efficient 4TPI (Threads Per Inch) pitch. This specific threading allows for rapid vertical adjustment without sacrificing load-bearing friction. Furthermore, as detailed in the technical specifications from image_ec0b3c.png, we offer the threaded outer diameter (OD) in 32mm, 34mm, and 38mm configurations, ensuring a perfect, zero-wobble fit inside your existing MS vertical scaffolding tubes.
Scalable Lengths and Heavy-Duty Jack Nuts
Every worksite has unique shoring requirements. To provide complete modular flexibility, our fork heads are available in five exact lengths: 400mm, 500mm, 600mm, 700mm, and 800mm. To support the vertical load during adjustment, buyers can specify their preference for either Casted or Forged Jack Nuts. The forged option provides exceptional impact resistance for heavy-duty industrial drops, while the casted nut offers reliable, cost-effective performance for standard commercial builds. By using strictly high-grade MS (Mild Steel), Shri Radha Enterprises guarantees that your shoring system remains secure, level, and entirely safe.

Application & Additional Information
Engineered for absolute precision in slab formwork and shoring, our heavy-duty MS fork head screw jack provides the ultimate U-shaped support for timber and steel primary beams. Manufactured from durable Mild Steel (MS) with a fast-adjusting 4TPI thread, this jack allows site crews to achieve millimeter-perfect height leveling. Available in extensive length configurations up to 800mm and equipped with heavy-duty casted or forged jack nuts, our scaffolding fork eliminates beam slippage and ensures optimal load transfer for demanding industrial concrete pours.
