Threaded inserts for your 3D printed parts

The ruthex threaded nuts can be subsequently inserted into parts of 3D printers, such as those from Anycubic, Creality, or Prusa, using heat or ultrasound. Through the heat of a soldering iron or ultrasound, the press-fit nuts are simply embedded into a blind or through hole.

Firm hold with easy handling

Thanks to the geometry of the threaded sleeve, it holds firmly in the printed part. The opposing spiral knurled nuts provide a balanced high tightening and loosening torque as well as high clamping force. The guide significantly facilitates insertion.

Stable & durable threads

The inserts with internal thread are made of high-quality brass, which ensures optimal corrosion resistance and thermal conductivity. This means that each press-in nut can be used for a long time and is easy to handle. The reusability of the screw threads is also possible by carefully removing them from the printed part when no longer needed.

Suitable for various plastics

The inserts are designed for all thermoplastics. The knurled nuts hold, for example, in PLA, PETG, ABS, PPS, PP, and many other materials. Once the plastic of the part cools around the brass sleeve and hardens again, the internal threaded sleeve is firmly anchored.

Practical threaded insert set

The ruthex threaded insert set RX-M4x8.1 consists of 50 press-in nuts with M4 internal thread and a length of 8.1 mm. The threaded sleeves can be embedded using ultrasound and heat.

Surviving a 8 month old heavy chewer
Color: Blue, Color: Blue
My dog is OK with it but doesn't like it as good as the whale indestructible toy I got her previously. She chews on it a little while and quits. She acts almost like it makes her nauseated. Idk though.... It gets very very sharp! Be careful grabbing it after they've chewed it.

AMAZING!
Color: Pink Blue
I have never written a review before, and I shop 4-5 days a week on Amazon. My 5 month old puppy LOVES these chew toys. When I first opened the box I was worried because they were so hard, but Poppy went crazy. He chews on them, tosses them and retrieves them, runs in circles around them and barks, and when he finally settles down will chew them and make these pig snort sounds of contentment. I have bought a lot of toys for my new puppy… But these are the best by far!

Toy broke in two
Color: Blue
This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.
