China Combination Screw Manufacturers, Suppliers, Factory

Every Carriage Bolt and Nut embodies advanced manufacturing processes and strict quality control. We use high-quality steel raw materials to ensure the strength and durability of our products from the source. During the production process, we use precise cold heading and hot forging techniques to shape and size bolts and nuts accurately. Advanced heat treatment technology also endows our products with excellent hardness and toughness.

The iconic design of Wing Nuts And Bolts lies in its unique butterfly shaped structure, with wing like protrusions extending from both sides of the head, resembling butterfly wings. This design overturns the traditional mode of nuts relying solely on tools for fastening, allowing users to quickly tighten or disassemble without the need for wrenches, sockets, or other tools, with high efficiency.

Grade 8.8 hexagonal bolts are made of high-quality carbon steel and undergo heat treatment to achieve a tensile strength of 800MPa and a yield strength of 640MPa, meeting the requirements of medium and high load scenarios. The nuts and washers are made of the same material or high elastic alloy steel to ensure long-lasting and stable locking force. The product is provided as a three piece set of "bolt+nut+flat washer" for driving.

The design of the Cross Pan Head Square Wash Bolt is exquisite, and its head shape is not only beautiful and generous, but also provides a comfortable point of contact during assembly, making it convenient for operators to tighten and greatly improving assembly efficiency. The design of the square pad is a major highlight of this screw. The square pad can provide a larger support area, effectively dispersing and avoiding damage to the surface of the connected part due to excessive pressure.

The Carriage Bolt Cone Nut Combination Screw achieves installation efficiency and connection strength through deep optimization of structure and materials. The wide load-bearing surface design of the cone nut increases the contact area between the bolt and nut, thereby increasing strength. Jinghong's advantage in providing customized carriage bolts and cone nuts lies in its unique cone locking structure.

The connection requirements in the industrial field are constantly changing, and different equipment and structures have different requirements for the specifications of bolts and nuts. Jinghong's Hex Nut And Bolt Set has a complete range of specifications, from diameter, length to thread specifications, which can meet various precise connection needs. The ability to accurately adapt enables JINGHONG hexagonal bolt nut combination products to be widely used in various industries.
