WHY THREADED INSERTS
  • Low installed cost
  • Blind installation
  • Permanent, reliable fastening
  • Eliminates the need for welding or tapping
  • Technically-advanced tooling systems

Avdel Cherry threaded inserts provide high-strength, load-bearing threads that are installed quickly and cost effectively into thin, thick, soft, hard and composite materials. The wide range of Avdel Cherry threaded inserts have been designed to meet and exceed the varied performance requirements of today's industry.

Avdel Cherry's threaded insert tooling utilizes leading-edge technology to provide a range of installation equipment, to best suit each applications requirements.

The combination of the extensive threaded insert product line and the wide range of in-house manufactured tooling, provides a unique fastening system to the end user. The advantages offered include:

  • Low Installed Cost
    The speed and ease of assembly reduces the cost of the product manufactured versus other methods of providing threads in thin sheet material.
  • Blind Installation
    One-side installation provides ease of placement and allows use in enclosed and solid applications.
  • Permanent, Reliable Fastening
    A secure and permanent fixing that is resistant to vibration.
  • Eliminates the Need for Welding Or Tapping
    Can be installed in pre-painted/pre-plated applications.
  • Technically-Advanced Tooling Systems
    Ergonomic hand and power tools with simple one-press trigger action. Automated placing equipment which save labor costs, balance manufacturing lines and deal with high-volume applications.

INSTALLATION

The installation of Avdel Cherry threaded inserts is easily accomplished with the use of our ergonomic, hand-held tooling through to fully automatic vibratory bowl feed equipment.

Setting Sequence:

1

2

3

  1. The insert is threaded onto the mandrel of the tool and then placed into a prepared hole.
  2. The mandrel then retracts into the tool which collapses the wall of the sheet, or by expanding the insert into the parent material.
  3. The mandrel then reverses from the threaded insert. The threaded insert is now installed.

SELECTING THE CORRECT THREADED INSERT

  1. The required performance of the insert such as torque to turn, push out, pull out or torque out will help determine the selection.
  2. Select the thread size.
  3. Measure the application thickness; i.e., the grip range required.
  4. Select the tooling and nose equipment.
