… is based on the proven triform geometry and offers a high
performance. This is achieved by the forming surfaces
at the furrow tip and the cylindrical screw shaft.
Due to a modified heat treatment and geometry under the
screw head, for example, it can also be used in high-strength and
rusty metal sheets can be used.
With a correspondingly reduced bore diameter,
for example in very thin-walled sheets, they form
automatically a pull-through.
Furthermore we offer for the furrowing in high strength
and austenitic sheets to Triform™ DB HF.
