Products Description
The center of the screw is empty, a feature that allows the screw to be guided with a guide pin during installation, ensuring precise positioning, especially in hard-to-reach or poorly sighted areas.The hollow part can also be used as a channel for wires, pipes or other small tools, increasing the versatility of the screws.
Cannulated Screws can be divided into several categories based on their design, use, head shape, and thread type.
By head shape:
1.Hex Head Cannulated/Hollow Screw: Has a hexagonal head for easy fastening with a wrench or socket wrench, common in industrial and mechanical applications.
2.Allen Head Cannulated/Hollow Screw: The head has a hexagonal hole and is fastened by an Allen wrench. It is suitable for the occasion when the screw head needs to be hidden.
3.Phillips Head Cannulated/Hollow Screw: The head has a cruciform slot and is fastened with a Phillips screwdriver.
4.Slot Head Cannulated/Hollow Screw: Use a flat-head screwdriver to tighten the screw.
5.Countersunk Cannulated/Hollow Screw: Flat head for applications that require the screw head to be flush with the surface.
Classification by use:
1.Orthopedic Cannulated/Hollow Screws: Used in orthopedic surgery, such as fracture fixation and joint replacement, usually made of biocompatible materials.
2. Mechanical Cannulated/Hollow Screws: Used for the assembly of heavy machinery and equipment to provide high-strength fastening.
3. Electrical Cannulated/Hollow Screws: used in electrical equipment, sometimes as the channel of the wire.
Products Application
1. Industrial and mechanical applications
Heavy machinery and equipment: Used to connect and secure heavy machinery components such as engines, drivetrains, housings, gearboxes and frames. Hollow designs are sometimes used through pins or dowel pins to help align parts.
Precision instruments and equipment: In assemblies requiring high precision, Cannulated/hollow screws provide fine-tuning and limiting functions, while their lightweight properties help reduce overall weight.
Aerospace: In the connection of structural components of aircraft and spacecraft, the low weight and high strength of hollow screws make them ideal.
Automotive industry: Used for the connection of automotive engines, drivetrains and body structures, providing reliability and easy maintenance.
Building and Structural engineering: In steel structural connections, used in Bridges, tall buildings and other structures requiring high strength fasteners.
2. Medical applications
Orthopedic surgery: Cannulated/Hollow screws are common implants used in orthopedic surgery to secure fracture sites, such as femoral neck fracture repair. Its design allows the use of guide pins to guide, ensuring accurate positioning.
Medical devices: In medical devices that require fine adjustment and maintenance, Cannulated/hollow screws can provide additional functionality and convenience, such as for securing sensors or instruments.
3. Electrical and electronic equipment
Precision electronics: In electronic devices that require frequent disassembly and maintenance, Cannulated/hollow screws provide an easy-to-operate connection, while hollow sections can be used to thread through wires and simplify internal wiring.
Communication equipment: In the assembly of antennas, cell towers and base stations, Cannulated/hollow screws can be used to connect metal structures to provide stability and weather resistance.
4. Other applications
Marine engineering: In the structure of ships and offshore platforms, screws are required to have good corrosion resistance, and the material choice of hollow screws can meet this demand.
New energy industry: In the assembly of wind power, solar panels and other equipment, Cannulated/hollow screws are used to connect and fix components.
Sports equipment: In the manufacture of bicycles, ski equipment and other sports equipment, Cannulated/hollow screws are used to hold key components in place while keeping the equipment lightweight.
Furniture manufacturing: In high-end furniture, Cannulated/hollow screws can be used for hidden connections, maintaining beauty while providing a solid structure.
When selecting a Cannulated/hollow screw, consider its material, size, thread type and head design to ensure it is suitable for the requirements of the specific application. In addition, for specific areas such as the medical and food industries, biocompatibility and hygiene standards must also be considered.
