nut?\u003c\/summary\u003e\u003cp\u003eIt is a hexagon flange nut with M8 thread made of A2 stainless steel, designed similar to DIN 6923. The flange has locking serrations that grip into the contact surface when tightened, thereby automatically securing the nut against loosening.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails class=\"sv-faq-item\"\u003e\u003csummary\u003eWhat is a locking serrated nut used for?\u003c\/summary\u003e\u003cp\u003eLocking serrated nuts are used wherever screw connections could loosen due to vibration or temperature changes. In PV mounting, they are used to connect profiles, clamps and brackets where a permanently secure screw connection is required.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails class=\"sv-faq-item\"\u003e\u003csummary\u003eDo I need an additional washer?\u003c\/summary\u003e\u003cp\u003eNo. Due to the molded flange, the nut distributes the contact force over a larger area, thus replacing the washer in many cases. The locking serrations also provide security against loosening.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails class=\"sv-faq-item\"\u003e\u003csummary\u003eIs the nut suitable for outdoor use?\u003c\/summary\u003e\u003cp\u003eYes.

Am Flansch sitzen Sperrzähne, die die Mutter beim Anziehen in die Auflagefläche krallen und so selbsttätig gegen Losdrehen sichern.\"}},{\"@type\":\"Question\",\"name\":\"Wofür wird eine Sperrzahnmutter verwendet?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Sperrzahnmuttern kommen überall dort zum Einsatz, wo sich Schraubverbindungen durch Vibration oder Temperaturwechsel lösen könnten. In der PV-Montage werden sie zum Verbinden von Profilen, Klemmen und Halterungen genutzt, wo eine dauerhaft sichere Verschraubung gefragt ist.\"}},{\"@type\":\"Question\",\"name\":\"Brauche ich zusätzlich eine Unterlegscheibe?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Nein. Durch den angeformten Flansch verteilt die Mutter die Auflagekraft auf eine größere Fläche und ersetzt so in vielen Fällen die Unterlegscheibe. Die Sperrzähne sorgen zugleich für die Sicherung gegen Losdrehen.\"}},{\"@type\":\"Question\",\"name\":\"Ist die Mutter für den Außeneinsatz geeignet?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Ja. Der Werkstoff A2 ist nichtrostender Edelstahl und damit korrosionsbeständig gegen Feuchtigkeit und Witterung. Die Mutter eignet sich daher für die Dach- und Freiflächenmontage von Photovoltaikanlagen.\"}},{\"@type\":\"Question\",\"name\":\"Wer ist Arres?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Arres ist ein Anbieter von Befestigungs- und Montagekomponenten für die Photovoltaik.
