Buttonfix Type 1 Metal fixings - Connects panels at 90 degrees and engages with a straight push
Four Buttonfix Type 1 Metal fixings holding a 70cm square panel survived 15g shock loads and only releasing the panel at 20g.
To put that in context, the drag racing world record of 4.4s over ¼ mile created 4.2g and the space shuttle generated a maximum of 3g during launch and re-entry.
Type 1 Metal is made from zinc which has a melting temperature of 440 Degrees C so is perfect for fire retardant panels.
In house tests show that when Type 1 Metal was face fixed with wood screws to plywood it failed at 300kg. So, assuming a 2 to 1 safety factor, a safe load for just one fixing would be 150kg.
Comprehensive independent test load data will be available shortly. Quick and easy to install, like all the fasteners in the Button-fix family
