Triangular Head RD Arc Thread Screw Rod for Jack

The triangular-headed RD arc-thread screw rod for jacks is a specially designed jack component featuring a triangular head and a unique RD arc-thread design, specifically used in jacks to achieve the lifting and lowering of heavy loads. The screw rod boasts a triangular head design, while its threads adopt the RD arc-thread design, which possesses a unique geometric shape to reduce friction, enhance wear resistance, and improve self-locking performance. The triangular head facilitates the use of specific tools for rotation, thereby improving work efficiency. The working principle of the triangular-headed RD arc-thread screw rod for jacks is similar to that of ordinary jack screw rods, both achieving the lifting and lowering of heavy loads through the rotation of the screw rod. When the screw rod rotates, its RD arc threads interact with the nut in the jack, converting rotary motion into linear motion, thereby pushing the jack's support point up or down.

We do not employ the traditional hot-cutting and striking process but instead utilize cold heading technology for one-time forming, ensuring stable quality, precise dimensions, and an even more exquisite appearance. Depending on customer requirements, we can use either carbon steel or stainless steel materials, and we can also tailor the product to achieve the corresponding strength level. Our screw rods can undergo surface phosphating, electrophoresis, and zinc plating to further enhance their strength.
