Head Design


  • Hexagonal Shape: The head is hexagonal in shape, which allows for even distribution of torque when tightening.

  • Socket Drive: The head includes a hexagonal socket that accepts a hex key (Allen wrench) or a hex bit driver for installation. This design helps prevent cam-out and provides high torque transmission without damaging the tool or the screw.


Shank and Thread Configuration


  • Extended Shank: The shank is longer than in standard cap screws, providing more engagement with the material being fastened.

  • Thread Type: Typically, these screws are fully threaded, but they can also come in partially threaded versions depending on the application requirements.


Materials and Finishes


  • Materials: These screws are commonly made from steel, stainless steel, brass, and other alloys, depending on the strength and corrosion resistance needed.

  • Finishes: Various finishes are available, such as zinc plating, nickel plating, black oxide, and others, to enhance corrosion resistance and appearance.


Application


  • Assembly: These screws are often used in assembly applications where the extended length is necessary, such as in machinery, automotive components, and industrial equipment.

  • Decorative and Functional: The hexagonal head provides a clean look while still allowing for secure fastening.

Installation Process
  1. Punch a Hole: Punch a hole in the material that is slightly larger than the diameter of the rivet nut.

  2. Insert the Rivet Nut: Insert the rivet nut through the hole from the front side of the material.

  3. Attach the Pull Cap: Attach the flat head hexagon pull cap to the rivet nut using a tool designed for this purpose.

  4. Pull and Set: Use the tool to pull the rivet nut into the material, causing the flaring ends to expand and grip the backside of the material securely.

  5. Remove the Pull Cap: Once the rivet nut is set, the pull cap can be removed, leaving a clean, flush-mounted nut on the front side of the material.
