## Description

ruthex M3 Threaded Inserts VORON - 100 Pieces RX-M3x5x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components: desertcart.com: Tools & Home Improvement

Review: Holds well, sized accurately too - I used these in some 3d prints and they worked great and held together. Their sizing is also accurate, as I double checked with some digital calipers. I was really bored and even counted how many came in the bag. The bag said 100, and I counted exactly 100. Not bad.
Review: Perfect for 3D Printed Toolheads and Parts - I am working on an EVA3 tool head for a Zero G Mercury 1.1 conversion and got these since they were the correct size from the bill of materials. They came neatly packaged in a bag and work as expected. They were easy to install with a heated soldering iron to push them in. The grip seems strong and the M3 screws thread perfectly through the inserts. Extremely happy with these and looking forward to using them to secure more prints and help me finish my conversion!

## Features

- M3x5x4 THREAD INSERTS FOR YOUR 3D PRINTED PARTS: The ruthex threaded nuts can be retrofitted by heat or ultrasound into parts of 3D printers from e.g. Anycubic or Prusa. With the help of heat from a soldering iron or ultrasonic, the insert nuts are simply embedded in a blind- or through hole.
- FIXED HOLD WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, the threaded sleeve holds it firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a balanced high tightening and loosening torque, as well as a high tightening force. The guide has made insertion much easier.
- STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread brass, which ensures optimum corrosion resistance and 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 thread insert set are lead free RX-M3x5x4 consists of 100 insert nuts with M3 internal thread, width 5 mm and a length of 4.0 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding.
