[initeq] 6-32 Threaded Heat Set Inserts for 3D Printing (Pack of 100, Short Length) Review

Nothing special about them other than they are PERFECT for my needs. They are MUCH smaller than they appear in the picture and fit all of my existing screws. and if you have 3D printers that require this, they give your models a very professional look.

I used .206" for the top hole and .185" for the bottom hole spaced .250". I also enlarged the .185" hole to the length of my bolt. For the screw I used The Hillman Group 101040 6-32" x 1-1/2" Pan Head Phillips Machine Screw, pack of 100. I did a stress test after installing it in a test box. I tried turning the bolt sideways to see if…
