E-Z Sonic Threaded Inserts for Plastic
E-Z Sonic ultrasonic threaded inserts for plastic are durable enough for the toughest environments and versatile enough to meet the needs of any application with superior torque and pull-out resistance. The brass thread inserts are designed for putting standard machine threads in 3D printed and thermoplastic parts. Install these metal thread inserts ultrasonically or with a heat driver. The tapered design simplifies installation. Available in tapered thread inserts in single and double vane, straight thread inserts in flush or flanged configuration.

They hold securely, threads are the right size and pitch, and easy to push in with a soldering iron. Just the ticket.

I did a test where I drilled the recommend hole and pressed in one insert into some maple and I moved over 3 inches and put some 5 minute epoxy in between and a light film on the knurl. I pressed this in and let it cure for 3 days. I inserted a 1/4-20 hex head bolt in 2" long and tightened the bolt down slowly. The insert held fairly well at first but eventually pulled right out. I moved over the in insert with the epoxy on it and I turned the bolt down and it started to get fairly stiff to turn. I kept turning and then I heard a pop and the thought that the insert came lose. No, it was the back side of the 1" maple creaking out as I screwed it down. The flat ended bolt split the maple about 3 inches before I saw any of the bolt. The insert is still in the board as strong as the day I put it in the male hole. There great insert and I feel that under the right circumstances and installation Technic will work very well in wood and not just plastic. Ten wahoo's the the folks who designed this insert. Great job!

If you do 3D printing you'll need heat set inserts. These are the style to get as they hold much better than the straight fluted ones.

The make the project look great with the brass ring showing. After heating with a soldering iron it when into the PLA+ very fast. I may have use too much pressure in pushing them in. So take it easy.

Brass is good for anti seize disassembly for outdoor or indoor use. When I install a threaded insert I like to use expanding gorilla glue to fill in the recesses and anti turn grooves on the insert . I thread a short screw or bolt flush with the base of the insert to keep glue out of the threads , moisten the area to be glued to activate the gorilla glue, apply the glue, install and trim the excess the next day. Great for installing elevator bolts to level a base on a project.

It's brass, threaded and knurled. Not much to see here but the thread quality and finish seems well done.

The outside diameter of the top of these inserts, the end you press against, is 9.6mm. That's a tad wider than my soldering iron with its tip removed. I can set them perfectly without using any special-purpose soldering iron tips. I still use the 6mm tip from my because I have them anyway.And, as long as we're talking dimensions, the inserts are 7.6mm long. You will, of course, want to make sure you are putting them into something at least that thick. Also, the diameter of the bottom end, the end that goes into the plastic first, is 9mm, should that be useful to your design.

Used in lots of 3d projects, easy to set with a insert tool or a soldering iron.
