HANGLIFE Heat-Set Threaded Inserts, M2 M2.5 M3 M4 M5 M6 Assortment Box (345 Pieces) Heat Set Insert for 3D Printing Components and Plastic Parts - Brass Metric Knurled Nuts

Great insert, works really well, wish we could buy them in larger quantity

Used for inserting into 3d prints. Had no issues and worked fine. Very easy to use and cheap. I used 300c on temperature for petg.

Good quality, good fit, good price, fast delivery. Large package will last forever.

Works great and dimensions are spot on

I recently got the HANGLIFE M2 heat-set threaded inserts, and they are just what I needed for my 3D printing projects! The quality is top-notch—these brass inserts are sturdy and durable, ensuring they won't break or deform easily.The installation process is straightforward: just heat them up and insert them into the tapered holes. Once the plastic cools, they hold firmly in place, giving me confidence in my designs.With their smooth, knurled surface and no burrs, they fit perfectly in my prints. Plus, they're compatible with various thermoplastics, making them versatile for different applications. I'm very satisfied with this purchase—definitely recommend these inserts for anyone looking to enhance their 3D printing experience!

These work well, dimensions given are accurate and there are plenty of them across a range of sizes. Perfect for adding threaded inserts to my 3d prints.

I bought this so that I'd have a nice "Assortment" of inserts for various future products. But there's nothing included to tell how to size the hole for each insert! I also separately purchased a package of additional M4 x 6 x 6 inserts, and that shows the actual specs - suggested width 5.31-5.35mm, minimum depth 7.0mm, minimum wall thickness 2.1mm. I'd never have known ANY of that without purchasing a separate set.

Needed for 3D printed parts, FPV Gimbal Sticks, etc.Worked GREAT and the best part is they're re-usable if you remember to take them out of bad/old prints allowing quite an "endless" supply if kept within your domina.
