High Strength Fastener DIN914 DIN913 Steel Hex Socket Cone Point Set Screw Grub Screw
Features:
Hexagon socket set screws, also known as Allen screws or hex keys, are characterized by their hexagonal socket heads. This design allows for precise tightening and loosening using a hex key or Allen wrench. The screws typically have a smooth shank without threads, making them ideal for applications where a tight fit is needed without generating thread stress.
Advantages:
- Precision Fit: The hexagon socket design ensures a precise and secure fit, minimizing the risk of slippage or cam-out.
- Easy Installation and Removal: Using a hex key or Allen wrench, installation and removal of these screws are quick and effortless.
- High Torque Transmission: The hexagonal socket allows for efficient torque transmission, ensuring a tight and reliable fastening.
- Low Thread Stress: The smooth shank design eliminates the need for threads, reducing stress on the material and increasing durability.
Application Scenarios:
Hexagon socket set screws are commonly used in a variety of applications where precision and reliability are crucial. Some common applications include:
- Machine Assembly: For securing and adjusting parts and components in machines and equipment.
- Electronics and Appliances: For fastening internal components in electronic devices and appliances.
- Furniture and Fixtures: For joining and securing pieces of furniture, cabinets, and other fixtures.
- Automotive Industry: For fastening components in vehicles, such as interior trim, dashboards, and other assemblies.
