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.

Look great and work just as well
No issues, great little threaded inserts with clean threads

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.

Indeed a #6-32 insert
I was worried initially this wouldn't fit my machine screws... I have a combination of electrician outlet screws and some long PC case fan screws that are both #6-32, and couldn't find a reliably cheap option. I bought the 10-piece set and it fits, so I'll be ordering a set of 100 now!

Five Stars

Wrong size
The 1/4-20 inserts from Initeq are awesome. I've stopped printing in spaces for nuts, and use these instead.I'm now returning my second pack of 6-32 inserts. The package is marked 6-32, but the inserts in the bag are actually M4. If I knew how to contact Initeq and verify they will ship me the right inserts, I would buy them again.

Great for 3D prints
Exactly what you’ll need in the world of 3D printing. Stake them in with a hot soldering iron and you’ll be smooth sailing. Seems to be the same quality as I’ve gotten from McMaster-Carr but at a fraction of the price.
