Speed Fastening


Why Speed Fastening?

  • Low installed cost - magazine-fed system
  • Reduced labor
  • Versatility
  • Reliability

The use of Speed Fastening in most applications has proven to be superior to other methods of fastening. Welding, sheet metal screws, nuts and bolts and pressed-in fasteners all require extensive labor. Speed fasteners are superior because of their:

  1. 1. Low Installed Cost: Up to thirty fasteners per minute (sixty with automated tools) can be set without any specialized labor.
  2. 2. Reduced Labor: The speed of placement can free operators to conduct tasks other than mechanical fastening.
  3. 3. Versatility: Speed fasteners are available in many types, sizes, and materials to meet the requirements of the most demanding applications - from automotive to electronic. Additionally, the Speed Fastening system permits "fine tuning," as the mandrel configuration can be altered to meet differing hole tolerances.
  4. 4. Reliability: Speed fasteners can permanently join applications and can withstand severe vibration and environmental conditions.

Installation

The installation of speed fasteners is easily accomplished using a range of tooling options, from simple handheld tools to continuously-fed placing heads, which are capable of functioning with robotic end effectors.

(Click on the picture above to see a demonstration.)

  1. 1. The fastener on a pre-loaded mandrel is inserted into the joint hole.
  2. 2. As the mandrel is pulled through the fastener body, radial expansion and clamp-up occur.
  3. 3. The mandrel pulls through the fastener. Installation is complete and the next fastener is indexed into position automatically.

Selecting the Proper Speed Fastener

  1. 1. Select a speed fastener that meets the shear and tensile requirements for the application.
  2. 2. Select a fastener material that is compatible with the materials being joined, and the environment to which the application will be subjected.
  3. 3. Determine the application hole size.
  4. 4. Measure the thickness of the material to be joined (grip).
  5. 5. Select the proper nose piece, mandrel and follower spring.
