[initeq] #6-32 Threaded Heat Set Inserts for 3D Printing (50, Long)
Description

- Securely and permanently add metal threads to 3D printed parts
- ›See more product details
Tapered threaded brass inserts for 3D Printing Easy to set in an appropriately-sized hole in the part using a soldering iron. Numerous vanes and ridges around the insert allow plastic to flow between them, creating a tough bond with the printed part. This is a much more versatile, durable, professional, and attractive solution than "captive nuts" and other solutions commonly employed when the need for metal threads in printed parts arises. One primary advantage these provide is the ability to design and print assemblies in multiple component pieces that attach with metal fasteners. This means that you can create products larger than the print volume your printer supports, and that failed prints often result in less waste due to only one part of a larger assembly failing. This also typically results in more "polished", professional-looking designs. Specifications: Thread Pitch: #6-32 Diameter: 0.206", tapering down to 0.185" OAL 0.250"

Strong bond in PLA
Works great. I was able to find the dimensions from a different product [initeq] Threaded Heat Set Inserts for Plastics Combination (Imperial + Metric) Assortment A 200 Pack . I used .206 in. for the top hole and .185 in. for the bottom hole, with a distance of .250 in. I also extended the .185 in. hole to the length of my screw. For the screw, I used The Hillman Group 101040 6-32-Inch x 1-1/2-Inch Flat Head Phillips Machine Screw, 100-Pack .I performed a stress test on this after setting it in a test block. I tried tweaking the screw sideways to see if the nut would come loose, but the screw bent. I then attempted to hammer on the screw from the back side (bottom side) of the nut test whether the nut would pop out. The screw bent, but the nut didn't budge. As a final test, I used a wrench to tighten the screw as far as I could. I expected the threads of the nut, being brass, would strip out or the nut would start spinning in the plastic. But... the head of the screw broke. :P I removed the remnants of the screw, and while there was slight damage to the threads, the nut still worked with a new screw without problem.I was a little surprised I was not able to get the nut to even budge in the block. I printed with PLA, 5 layer outlines. I think this certainly helped to retain the nut. To insert the nut, I used my Weller WESD51 set to the lowest heat setting, which is 350 F. I didn't force the nuts in, but allowed the weight of the soldering iron to work the nut into position.The only way these nuts are coming out of the PLA block is with heat. I'm pleasantly impressed with these, and this should allow me to expand the types of projects I can create with my 3D printer.

Well made, work nicely.
I turned down a soldering iron tip in my lathe to fit this, so I can melt them in easily.I have used them for two purposes - to put threads in 3D prints, and to use as a replacement for Helicoils that stripped out the existing threads in plastic. They can also be epoxied in place.

Simply Awesome
There is not much to see about this other than they work PERFECTLY for my needs... They are MUCH smaller than the picture suggests and they fit all of my existing screws... and if you have 3D prints that need these, they do class up your models with a very professional look.
