Paneltwistec, washer head FT A2

The Paneltwistec fully threaded screw maximises the load-bearing capacity of connections thanks to its high thread extraction resistance. It is, of course, suitable for timber-timber and steel-timber connections but has been specially designed for connections between our solar roof hooks and rafters. Thanks to the screw tip’s special geometry with a self-clearing groove a splitting effect during screwing in is prevented; what’s more the screw-in resistance is also reduced. Thanks to the large head diameter, significantly higher tightening and head pull-through values are achieved.
