ruthex M8 Threaded Inserts - 20 Pieces RX-M8x12.7 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

Overall, I’m very happy with these heat inserts. They shipped quickly and arrived in good condition with no issues. In use, the machining appears to be high quality and the knurling is clean and consistent. Screws thread in smoothly without binding or cross-threading. I primarily use these for 3D printed parts and have not experienced any fitment or durability problems. They perform exactly as expected and I would recommend them to anyone installing threaded inserts in 3D prints.

Impressive. Worked very well, easy to press in. Threads nice and clean.

I have used Ruthex before. No problems. The inserts hold very well in #D prints. Recommended. Thanks.

I've never had any trouble setting these with my soldering iron. I don't use any additional tools, jigs, or presses. Pretty easy stuff They work well and don't come out. Big fan

Went through the pack in a week. Very high quality and the specs on the front are exact especially for 3d prints. Great value and they fit great and are very strong. I used them for an outdoors application and they are showing no wear or movement.

Love having a variety so I can use what's needed for different projects. Lot better to screw into verses plastic. Makes a strong connection.

Quality inserts, but the case came with no latch to keep it closed, so It's pretty much useless.

I used them for inserts on cabinet doors and drawers and then epoxied 8/32 flat head machine screws to river rocks, nice pulls for under 20 bucks. Stainless steel tubing to cover threads.

Dobry produkt, w dobrej cenie, szybka wysyłka, jestem zadowolony

品質がとても良く、樹脂への食いつきも抜群です。ネジの締め込みもスムーズで、ガタつきや緩みなどの問題はまったくありません。3Dプリント部品への固定にも安心して使える、高精度で信頼性の高いインサートです。

I use these in every single 3D printed enclosure I design and they are perfect. Just finished off a bag of M3's and I've ordered some M4 and M5
