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:
- Low Installed Cost: Up to thirty fasteners per
minute (sixty with automated tools) can be set without any specialized
labor.
- Reduced Labor: The speed of placement can free
operators to conduct tasks other than mechanical fastening.
- 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.
- 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.)
- The fastener on a pre-loaded mandrel is
inserted into the joint hole.
- As the mandrel is pulled through the fastener
body, radial expansion and clamp-up occur.
- The mandrel pulls through the fastener.
Installation is complete and the next fastener is indexed into position
automatically.
Selecting the Proper Speed Fastener
- Select a speed fastener that meets the shear
and tensile requirements for the application.
- Select a fastener material that is compatible
with the materials being joined, and the environment to which the
application will be subjected.
- Determine the application hole size.
- Measure the thickness of the material to be
joined (grip).
- Select the proper nose piece, mandrel and
follower spring.
