In weichen, verformbaren Werkstoffen wie Stahl, Druckguss, Kupfer, Buntmetallen und Leichtmetallen können statt Schrauben und Muttern selbstschneidende Schrauben – auch selbstbohrende Schrauben genannt – für feste Verbindungen sorgen. Diese Spezialschrauben formen beim Einschrauben das Muttergewinde selbst. Das hat in der Montagepraxis eine Reihe von Vorteilen:
- Es wird kein Gewindebohrer benötigt, die Werkzeugkosten sinken.
- Der Arbeitsschritt des vorangehenden Gewindeschneidens entfällt, was die Montagekosten reduziert.
- Es ist keine Kontrolle des Muttergewindes erforderlich.
- Zusätzliche Schraubensicherungen sind in der Regel unnötig.
- Die Flächenpressung sorgt für einen guten elektrischen Kontakt.
Schraubverbindungen mit selbstschneidenden Schrauben werden auf drei Arten hergestellt. Gewindefurchende Schrauben verdrängen das Material in der Kernbohrung: Es wird spanlos kaltverfestigt (Taptite®-Prinzip). Gewindeschneidende Schrauben werden in der Regel in ein vorgebohrtes Kernloch geschraubt und schneiden das Gewinde dabei spanend. Gewindebohrende Schrauben schließlich bohren auch das Kernloch mit ihrer Bohrspitze selbst, das Gewinde wird spanlos geformt. Im ETTINGER-Sortiment finden Sie selbstschneidende Schrauben in zahlreichen Ausführungen und speziell für Ihre Werkstoffe.
Direktverschraubung für Metalle, Duroplast, Thermoplast
Für Metalle erhalten Sie spanlos gewindefurchende Senkkopfschrauben nach DIN 7500 (Form M). Ihre minimale Zugfestigkeit beträgt 800 N/mm2. Sie sind aus Einsatzstahl oder rostfreiem Stahl A2 gefertigt und standardmäßig mit Innensechsrund (Torx®) oder Kreuzschlitz-Pozidriv lieferbar. Diese gewindeformenden Schrauben für Stahl und Alu erhalten Sie auch mit Linsenkopf. Beachten Sie auch unser umfangreiches Angebot an Blechschrauben nach ISO-Norm – mit Zylinderkopf, Senkkopf oder Linsenkopf (Flachkopf auf Anfrage) – sowie für gewindeformende UNC-Schrauben mit angepresster Scheibe und Sechskantkopf.
Für dauerhafte und werkstoffgerechte Kunststoffverbindungen liefern wir selbstschneidende Schrauben als gewindeformende Variante für Thermoplast und Duroplast aus Vergütungs- bzw. Einsatzstahl sowie verzinktem oder rostfreiem Stahl A2, ebenfalls mit verschiedenen Antriebsarten und Köpfen. Die Spezialgewinde haben eine hohe Klemmkraft bei geringem Kraftaufwand beim Einschrauben. Durch den kleinen Flankenwinkel wird bei den Linsenkopfschrauben Delta-PT eine minimale Radialspannung erreicht. Die optimierte Steigung sorgt für eine große Selbsthemmung im Gewinde. Diese Schraubentypen sind auch mit Scheibe erhältlich.
Die selbstschneidenden Schrauben bekommen Sie in zahlreichen Abmessungen und großen Stückzahlen direkt ab Lager. Bestellen Sie einfach online.
