Schraubenkopf mit Senkschneide Die herkömmlichen Schraubensenkköpfe haben den Nachteil, beim Andrehen der Schrauben( ohne vorhergehendes Senken, was in der Praxis aus Zeitgründen meistens unterbleibt ) z.b. beim Anbringen von Latten- Unterkonstruktionen ftir Arkustikdecken ( Paneele, Provilbretter, Fassadenplatten, Dämmplatten usw. ) die Latten aufplatzen, bzw. aufreißen und repariert, bzw. ausgewechselt werden müssen. Screw head with countersunk cutting edge The conventional screw countersunk heads have the disadvantage when turning the screws (without first countersinking what in practice mostly omitted due to time constraints) e.g. when attaching battens Substructures for acoustic ceilings (panels, provil boards, facade panels, Insulation boards etc.) the slats burst or tear open and repaired or replaced Need to become.

Bei der Erfindung des Schraubenkopfes mit Senkschneide entstehen die obengenannten Nachteile nicht.With the invention of the screw head with countersink the the disadvantages mentioned above do not.

Beim Schrauben in alle Materialien, welche eine geringere Festigkeit als die Senkschneide haben, zb. Holz, Plastik, Kunststoff, Asbestzement usw. senkt sich unser Schraubenkopf mit Senkschneide selbst ein, indem er das Material nicht verdrängt (und ein Aufplatzen, Aufreißen verursacht} sondern durch Spanabhebung entfernt, ähnlich dem Ansenken.When screwing in all materials which have a lower strength than have the countersink, e.g. Wood, plastic, plastic, asbestos cement, etc. lowers our screw head with countersunk cutting edge inserts itself by not removing the material displaced (and causes a rupture, tearing) but by chip removal removed, similar to countersinking.

Bei der Erfindung des Schraubenkopfes mit Senkschneiae hat man den Vorteil in ( Holz, Plastik, Kunststoff, Asbestzement, Glasfieber usw. ) nicht ansenken zu müssen ( enorme Zeitersparnis, geringerer Kraftaufwand, reduzierung der Unkosten ). Man hat keine Reparaturzeiten, keine Materialverschwändung bei zb. ( Dachlatten ) usw. )With the invention of the screw head with countersunk blade, you got that Do not lower the advantage in (wood, plastic, plastic, asbestos cement, glass fiber, etc.) to have to (enormous time savings, less effort, reduced costs ). There are no repair times, no waste of material for example. (Roof battens ) etc.)
