Why Speed Fastening?
- Low installed cost - magazine-fed system
- Reduced labor
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. Low Installed Cost: Up to thirty fasteners per minute (sixty with automated tools) can be set without any specialized labor.
- 2. Reduced Labor: The speed of placement can free operators to conduct tasks other than mechanical fastening.
- 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. Reliability: Speed fasteners can permanently join applications and can withstand severe vibration and environmental conditions.
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. The fastener on a pre-loaded mandrel is inserted into the joint hole.
- 2. As the mandrel is pulled through the fastener body, radial expansion and clamp-up occur.
- 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. Select a speed fastener that meets the shear and tensile requirements for the application.
- 2. Select a fastener material that is compatible with the materials being joined, and the environment to which the application will be subjected.
- 3. Determine the application hole size.
- 4. Measure the thickness of the material to be joined (grip).
- 5. Select the proper nose piece, mandrel and follower spring.
