Material: Made of premium brass, anti-rust with good thermal conductivity
Firm & Stable:The opposing spiral-shaped knurled design on the side of the nuts can increase the friction and ensure firm embedding in various plastics such as PLA, PETG, ABS, PPS, PP, etc. The threaded inserts will be securely fixed once the plastic of the parts surrounding the brass sleeve cools and hardens
Easy to Install: The threaded nuts can be retrofitted by heat of a soldering iron or ultrasound into a blind or through hole of 3D printer components. Compatible with Anycubic, Creality, or Prusa 3D printers
Heat-set Insert Tips: We have soldering adapter tips help set the threaded insert into the plastic by heating the tip without touching the thread inserts, increasing the strength of the part without causing sticking or damaging after injection molding
