About this item
- Package includes: 300pcs threaded inserts in metric sizes M2,M2.5,M3,M4,M5,M6,1/4-20 to meet your different needs, 7pcs welding adapter facilitates easy installation of the threaded inserts, ensuring a secure and precise fit.Comes with a labeled divider box with detailed annotations of sizes and quantities to keep all components neatly organised and easily accessible
- 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

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
