in-saiL 100pcs/lot M3x4.0mm, OD4.6mm Heat Staking Threaded Insert Quik-Tek Brass C3604

Love these things, theyre so good I use them so much I keep coming back for more. 10/10 will threaded insert again

They are what theyre supposed to be...

They do what they are supposed to do! What can I say, they are as described.

I originally purchased these to build the Hero Me Gen6 and have no complaints. They were easy to put in with my soldering iron. I have used these for multiple projects and havent experienced any issues with the insert slipping out or rotating.

Easily melts into a 4mm hole in a 3d print, and holds way better than threading into the plastic.

These are perfectly sized

Very easy to install with use of a soldering iron and some pressure applied to a 3d printed part. Used mostly with PLA parts for mating enclosures.

If you 3d print you need these...

These are perfect for the Hero Me Fan system. They are of good quality. Highly recommend them.

Worked for my 3d printing projects. Easy to insert, sits tight.
