• 100 RX-4-40x5.7 threaded bushings made of brass
• Sturdy press-in nut
• Can be inserted into 3D printed parts made of plastic using heat

#4-40 threaded inserts for your 3D printed parts:
Using heat or ultrasound, these threaded nuts can be retroactively inserted into parts created by 3D printers, such as those from Anycubic, Creality or Prusa. The press-in nuts are easily embedded into a blind hole or through-hole using ultrasound or heat generated by a soldering iron.

Firm hold and simple application:
The geometry of the threaded sleeve means that it holds firmly in the printed part. The helical knurled nuts opposite ensure a high, balanced tightening and loosening torque and high tightening force. The guide makes insertion significantly easier.

Sturdy and durable screw-in threads:
The inserts with internal threads are made of lead-free brass of the highest quality, which ensures that they have optimal corrosion resistance and heat conduction properties. This means that each press-in nut has a long service life and is easy to use. The screw-in threads can also be reused by carefully removing them from the printed part whenever it no longer happens to be of use. ...
