TRIFORM

… are thread-forming screws for metal components.
They have been proven for many years and are characterised by low
and good thread load capacity.
This is achieved by the combination of low-cost production
Triform™-Through point and round shaft cross-section.

TRIFORM DB

… 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.

PLASTIC FORM

… is a mathematically and experimentally optimised thread for
Screwed connections in plastic. The geometry is especially
low screw-in torques. Due to the thread geometry
results in high tear-out forces.
Plastoform screws are mostly used where highest
requirements for the screw connection must be fulfilled.
Plastoform screws are suitable for both ductile and
brittle plastic direct screw connections are suitable and have a
high dynamic load capacity.

PR

The PR thread profile was developed for screwed joints where
medium requirements must be implemented.
The screw has narrow 30 degree flanks, which in plastic have a good
Overlap between screw threads and formed nut threads
lead.

The core diameter is selected so that the plastic is generally
does not flow to the root of the thread.
