Product Details

The core of this product’s functionality lies in its dual-purpose design. The hardened, thread-rolling tip cuts into the host material, displacing it to form strong, clean internal threads as the screw is driven. This process, known as thread forming, creates a zero-clearance fit that offers exceptional resistance to loosening and pull-out. The external hexagon head provides multiple points of contact for driving tools, allowing for the application of significant torque without the risk of stripping that can occur with other drive types.

We offer these screws in various steel grades to meet different strength requirements, from general-purpose Class 4.8 (made from materials like C1010 carbon steel) to high-tensile Grade 10.9 for structural and high-stress applications. To ensure longevity and performance, the screws are available with high-quality protective coatings, including blue zinc plating and galvanization, which provide excellent corrosion resistance.

Product Features

Our Hexagon Head Self-Tapping Screws are designed for superior performance, offering several key benefits:

• High-Torque Installation: The external hexagon head allows for the use of standard sockets and wrenches, enabling high clamping force and a secure joint.
• Eliminates Tapping Operation: The self-tapping, thread-forming design saves significant time and labor by cutting its own threads, streamlining the assembly process.
• Versatile Strength Options: Available in standard (Class 4.8) and high-strength (Grade 10.9) steel, making them suitable for a wide range of load-bearing requirements.
• Excellent Corrosion Resistance: Finished with a durable zinc or galvanized coating to protect against rust and environmental corrosion, extending the life of the assembly.
• Superior Holding Power: The thread-forming action creates a tight, precise fit with the material, providing exceptional resistance to vibration and pull-out forces.
• Quality Manufacturing: Produced using advanced thread-rolling techniques for stronger, more uniform threads and subject to rigorous quality control checks.

Product Applications

The robust nature and high clamping force of these screws make them ideal for a variety of industrial applications, including:

• Industrial Machinery and Equipment: Assembling frames, mounting components, and securing panels.
• Metal Fabrication: Joining sheet metal, steel plates, and structural profiles.
• Automotive and Transportation: Used in chassis assembly and for mounting heavy components.
• Construction: Fastening metal roofing, cladding, and steel framework.
• HVAC Systems: Securing ductwork, mounting brackets, and assembling units.
