Review: Dobry produkt, w dobrej cenie, szybka wysyłka, jestem zadowolony
Review: Lieferung: schnell, gut verpackt, alles bestens. Produkt wie beschrieben, macht einen wertigen Eindruck. Passt problemlos auf einen Standard-Lötkolben mit 900M-Spitze. Gute Idee, die kleinen Aufsätze aufschraubbar zu designen, erleichtert den Wechsel, wenn man mit unterschiedlichen Gewindedurchmessern arbeitet. Die Spitzen kommen schnell auf Temperatur, wir stellen den Regler meist zwischen 120 und 190 Grad Celsius ein, je nachdem, in welches Material die Gewinde eingeschmolzen werden. Bei PLA funktioniert es sehr gut. Bei Peli-Koffern wird das Material schnell weich, fliesst aber nicht ganz so gut an den Gewinden, die Stabilität ist aber mehr als ausreichend. Es ist schon erstaunlich, welche Zuglasten die Verbindung zwischen PLA und Gewinde aushält. Ein M2x2,5-Gewinde in einer PLA-Struktur mit 2 Aussenschichten hält locker 10 kg Zug aus. Wir benötigen die Gewinde für Geräte, die an PLA-Drucke geschraubt werden und später gewechselt / abgeschraubt werden sollen. Das Einschmelzen der Gewinde ist eine einfache, stabile und sehr ansehnliche Lösung.

## Features

- 1/4" THREAD INSERTS FOR YOUR 3D PRINTED PARTS: The ruthex threaded nuts can be retrofitted by heat or ultrasounds into parts of 3D printers from e.g. Anycubic or Prusa. With the help of heat from a soldering iron or ultrasounds, the knurled insert nuts are simply embedded in a blind- or through hole
- FIRM HOLDING WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, it holds firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a high balanced tightening and loosening torque, as well as a high tightening force. The guide, insertion has been greatly simplified
- STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread lead free brass, which ensures optimum corrosion resistance and thermal conductivity. thermal conductivity. This means that each insert nut can be used for a long time and is easy to use. The reusability of the insert nut is also possible by carefully removing them from the pressure part when they are no longer needed
- SUITABLE FOR A VARIETY OF PLASTICS: The inserts are designed for all thermoplastics. For example, the knurled nuts hold in PLA, PETG, ABS, PPS, PP and many more. As soon as the plastic of the part around the brass sleeve cools and hardens, the threaded sleeve is firmly anchored
- PRACTICAL THREAD INSERT SET: The ruthex threaded inserts set are lead free and RX-1/4“-20x12.7 consists of 20 insert nuts with 1/4" internal thread and a length of 12.7 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding
