Prasacco 100 Pcs M3 Threaded Insert M3 Heat Set Inserts 3D Printing Brass Nuts Knurled Twill Thread Nut Inserts for Loptop Automotive Plastic Shells

was a good screw

nice

Ordered these for a 3d printing project. They work a treat. Easy to insert using a soldering iron with a pointed tip in the middle. Takes a bit of practice to get them straight but that's the same for any brand of these. And they work just fine. Can't fault them - good value for a big bag full of inserts!

I'm sure these have other uses but, for 3D printed projects, these transform how easy it is to construct boxes and cases. For the M3 nuts I set blocks of 10 mm cubed with a 4mm hole in them (6mm depth), placed a rivnut in the hole, put a soldering iron on top of the nut and then gently pushed down. The nut settles in with a very satisfying squelch and then it's an extremely strong anchor to screw other components, plates or faces onto. Love these and I'll be using them in all my medium-to-high complexity 3D projects from now on! Recommended.

Perfect size thread and clean knurling

work very well good price

junk

thank you great

Die Hewindeeinsätze können einfach mit dem Lötkolben eingebracht werden, zumindest in Plastik. Die Gewinde selbst sind passend und die Schraube geht leichtgängig rein.
