Your cart is empty. Pack of 200 threaded inserts. These create much more convenient and professional parts than using "captive nuts" (where you have to design a slot for a nut, and then place the nut in the slot and hold it there while affixing a screw). They also can be used in some situations where captive nuts just don't work. These are inserted into a hole in the print that is slightly smaller than the insert, and set in place using a soldering iron to melt the plastic around the insert. The inserts have a slight taper and small fins that the plastic flows around, resulting in an extremely strong bond.
Rather than adjust designs around the limitations of 3D printing (supports, print bed size, etc), divide your parts into separate components that fasten using these inserts and machine screws. Not only does this give you greater flexibility when designing a part, but also allows you to re-print only failed components rather than full assemblies - saving time and money.
Tips:
- Hole size in your product should be slightly smaller than the insert, to allow plastic to flow between the insert's vanes.
- Allow the insert time to heat up prior to inserting into the plastic part. The plastic needs to fully melt around the insert and flow between the "fins" for a strong bond

Bought this because I needed some m5 inserts, when it arrived it had some m6 where the shorter m5 should be, so I built the print around the larger m5 that had an OAL of 6.73mm. Struggled to get a successful print in 80-90% humidity only to find out that the actual measurement of the longer m5 is actually 11mm. So in conclusion their "measurements" are worthless, and this is just an assortment of garbage that may or may not have what you need.

The inserts work very well, make sure the holes in your part are designed to the correct size.

Mucho mas caras que las metricas, pero hacen lo que tienen que hacer y son las unicas SAE que pude encontrar despues de buscar mucho. Tienen el diseño ideal para impresiones 3D (por las rayas diagonales) pero no acabo de entender el precio...

Units were just what I needed for my 3D printed projects. Threads look to be in good form. And the packaging is surprisingly nice and easy to read (inserts sizes) and use (enough space to get inserts out without dumping the bin.)

Its a mixed back of different types of heat set inserts. Some hare the tapered kind that work well with 3d prints and some are the uniform width type used in injection molding. The injection molding ones suck.

My immediate need was for 2 of these to repair an oven door handle that was falling off. The mfr. used self-tapping screws, one of which had been constantly loosening and finally became completely stripped out. The other end of the handle was not far behind. The screws in question were #10. Since I only needed 2, and my choices were to either buy a much larger quantity of just 10-32 inserts or get the assortment, I opted for the assortment, thinking that it might be handy to have other sizes for future projects.The "gotcha" was that I could find no heater tip listed for #10 inserts. My solution was to take a beat-up old soldering tip for my old Weller iron and chuck it up in my drill press (think: poor man's metal-working lathe ;) Then, spinning the tip at a moderate speed, I shaped it using a metal file. It didn't take long since underneath the tip's plating (nickel, I'm guessing) the tip is solid copper and "machines" easily. I put a nice square shoulder on it for pressing on the (relatively large) insert. (See pic.)Let me tell you, it worked like a charm -- the inserts went into that plastic handle "like buttah". I picked up a couple of 10-32 x 2" machine screws at the local hardware store, reassembled the oven door, and now it works like new if not better than! So far, the handle has a very solid feel and I don't anticipate the inserts pulling out any time soon.

These little guys work great. I make the hole right in the middle of the suggested size for diameter. I will get some plastic oozing up. Trim it off with a razor and you after good to go.

It is as expected at a great price. The image makes it look bigger than a small 6 inch long tray though. You loose a star for a misleading picture that does not have dimensions. You know that picture makes it look big and your taking advantage of buying online.

I'm installing these inserts into 3D printed parts and they work wonderfully. I really like the fact that a nominal hole diameter is printed on the inside of the box lid. It's a very handy reference when I'm designing parts and need to know what diameter of hole to use.I bought a special soldering iron tip to aid in installing these and it works well, just fire up the iron, position it and the insert of choice on the hole to be used, and gently press the insert in as the iron heats up.
