Introduction
In modern mechanical manufacturing, electronic devices, furniture assembly, and numerous other industrial fields, screws play an indispensable role as key components for connection and fixation. Among them, non-knurled cup head hex socket three-combination screws have become the preferred choice for many engineers and craftsmen due to their unique design and versatile functionality.
Structure and Features of Non-Knurled Cup Head Hex Socket Three-Combination Screws
Non-knurled cup head hex socket three-combination screws consist of three main parts: the cup head, hex socket, and screw shaft. Their features are as follows:
1. Cap Head: The cup head is typically cylindrical and smooth without knurling, hence the name "non-knurled cup head." This design ensures that the cup head does not cause additional damage to the contact surface during installation, making it suitable for applications that require high precision and aesthetics.
2. Hex Socket: The hex socket is located at the top of the cup head and is designed to accommodate a hex key (Allen wrench) for tightening or loosening the screw. This design allows the screw to withstand high torque during installation, making it suitable for high-strength connections.
3. Screw Shaft: The screw shaft is usually fully or partially threaded, with a variety of thread specifications available to meet specific requirements. The material of the screw shaft is typically high-strength alloy steel or stainless steel, offering excellent tensile strength and corrosion resistance.
Usage Method of Non-Knurled Cup Head Hex Socket Three-Combination Screws
1. Preparation: Before using non-knurled cup head hex socket three-combination screws, it is necessary to prepare the appropriate tools, including hex keys, screwdrivers, and torque wrenches. Ensure that the materials and specifications of the components to be connected meet the design requirements.
2. Installation Steps:
Step 1 : Insert the screw shaft into the component to be connected, ensuring proper alignment of the threads.
Step 2: Insert the hex key into the hex socket of the cup head and turn the key clockwise to gradually screw the shaft into the component.
Step 3: During tightening, use a torque wrench to control the torque, ensuring that the screw reaches the specified tightening torque to avoid over-tightening or under-tightening.
Step 4: After tightening, inspect the connection to ensure it is secure and free from any looseness.
3. Disassembly Steps:
Step 1: Insert the hex key into the hex socket of the cup head and turn the key counterclockwise to gradually loosen the screw shaft.
Step 2: During disassembly, take care to protect the surface of the component to avoid scratches or damage.
Step 3: Once the screw shaft is completely unscrewed, inspect the condition of the component to ensure there is no damage or deformation.
