Plastic joinery systems have been all the rage in the last few years, offering a wide variety of options for using
simple plastic bits to connect panels
and parts. But, let’s face it, plastic
does have its limits in some joinery
applications, such as high-vibration or
fire-rated applications. Responding to
that issue, the makers of the Button-fix
system have expanded with a new line
of all-metal connection hardware.
We previously reviewed the original
plastic Button-fix hardware more than
a year ago. The straightforward system
developed in the United Kingdom uses
a simple grooved round button that
mates with several receiver plates with a
quick and secure snapping connection.
Advantages of the Button-fix system
included ease of installation (no CNC
required, although one can be used),
forgiving alignment, and a diversity of
But now with an all metal application, the joinery can stand up to more
demanding application scenarios. With
all-metal construction, including a
metal spring that gives a solid “click”
when the button slides home in its fitting, the new Type 1 Metal Button-fix
offers added security. The manufacturer claims the unit will withstand 15,000
connections without failure.
They’ve even had it tested by an
Button-fix goes heavy metal
independent lab (Engineering Dynam-
ics) to see how it withstands severe
vibration. They subjected a panel
mounted on four Type 1 Metal Button-
fixes to vibrations ranging in frequency
from 5Hz to 400Hz and up to 30
minutes in duration. The Button-fixes
remained connected throughout.
They also performed a series of
shock load tests, showing the fasten-
ers could hold out against even a 15g
shock. That’s five times the shock ex-
perienced by Space Shuttle astronauts
on lift-off (3g) and nearly twice what a
fighter pilot might experience in dras-
tic maneuvers (up to 9g). Ultimately
the fasteners decoupled at 20g, but I’d
hate to think what that kind of shock
would entail. Check out their video
and see what you think.
Button-fix hardware is available in
North America through Hafele and
other distributors. For more informa-
