M2, M2.5, M3, M4, M5 tips compatible with Hakko FX888D soldering iron
Designed and manufactured in the USA
Compatible with the Hakko FX888D irons.
M2, M2.5, M3, M4, and M5 sizes.
Greatly increase connection strength between 3D printed parts.
Heat set insert installation tips compatible with Hakko FX888D soldering irons
Strengthen and connect 3D printed and injection molded parts
Heat set inserts are a great way to improve connection strength between 3D printed parts.
Don't ruin your 3D printed part by messing up the insert installation. Our installation tips have a square shoulders and vertical walls that let them slide back out of the insert without catching or pulling the insert out accidentally.
Long shank allows you to reach deep into 3D printed parts.
Slender shank allows insert installation into tight corners without melting the side plastic.
Vertical wall allows easy release of insert once installed.
Square shoulder makes it easy to know if the insert is installed straight.
A must-have for every 3D printer toolbox. Not intended for soldering. Soldering iron not included.
How do you use heat set inserts?
Design your part with holes for inserts
Create your design with holes or pre-drill holes for where the insert is going to be placed. These holes need to be a little smaller than outer diameter of the insert and about 10-15% deeper than the length of the insert so that plastic will melt, deform, and mold around the insert properly. You may need to experiment with your 3D printer as some are not very accurate and the inserts themselves can have different outer diameters even if they are the same thread size.
Heat iron to plastic melting temperature
The hotter the iron, the faster the melt will happen. This may be desirable in a production environment. If you are a beginner, set the temperature right at the melting temperature of the plastic you're using or the extrusion temperature of your 3D printer.
ABS - between 490 and 700 F
PLA - 356F to 428F (180 - 220 C)
If the plastic begins to smoke, lower the temperature. If no melt happens or too much pressure is required, raise temperature.
Horizontal method-See listing video
If an insert is placed onto the tip when the iron is horizontal, you can press the insert directly into the piece if you keep the iron horizontal. Because the tip is designed to not hold onto the insert, if the insert is placed on the tip and then oriented vertically, the insert will fall off. Holding the piece in one hand and using the iron with the insert on the tip in the other hand and pressing horizontally. This is our favorite method.
Vertical method-See listing video
If installing with the iron horizontal is not convenient or too difficult, you may need to install the insert in a vertical orientation. Place the insert over the hole it's going into first taking care to make sure the insert is sitting square over the hole. Use some needle nose pliers to hold it there, if you need to. Then use the tip of the iron and place it inside the insert and begin to lightly press down until the insert begins to melt the plastic and moves into position. Simply pull the iron straight back up and out when the insert is in the proper place.
How do I replace the soldering iron tip with the insert installation tip?
Unscrew the collar nut that holds the tip retaining sleeve
Make sure the iron is turned off and cooled down. Turn the nut with the knurling counter clockwise to loosen until it's free. Take the nut off the iron by moving it toward tip end of the iron. Remove the retaining sleeve by pulling it towards the tip end of the iron.
Remove the soldering tip which is over the ceramic heating element
Simply slide the old tip off the ceramic heating core.
Place the new insert installation tip over the heating element
Guide the heating element into the 5/32" hole in the insert tip and position the tip as far down as it will go.
Place the sleeve back over the tip and screw on the collar nut
Place the retaining sleeve back over the wand. Bring the collar nut back over the sleeve and rotate the nut clockwise finger tight.
Why use a specific size of tip?
It's important to pair the correct size of tip with the size of insert you are using. If the tip is too small for the insert, plastic will come back up inside the threads making it very difficult to turn your screw into the insert. Many times your part can be ruined because it's difficult to replace an insert if the surrounding plastic is deformed. We created these specific sizes because they are some of the most popular sizes and they are precision machined to be exact fits with just enough clearance that they don't pull the insert back out, but not so much clearance that plastic comes inside the threads. The right tool for this job requires the right size tip and this set has the most popular metric sizes.
Common questions
Where can I find inserts?
Search for "Heat set inserts". It's best if you use the "conical" shaped inserts, those with a wider top than bottom. Those are the inserts designed for heat-set.
I don't have a Hakko FX888D
There are hundreds of iron types and even more tip types. If it is a Weller SP40NUS these tips will fit. If you have a Weller WES51 we have a model of ET Series tips that will fit that iron. Search for ASIN# B08LQTD21D.
How long are these tips?
Total length on these tips is 1.6 inches or 40.6 mm. On a Hakko FX888D these tips reach 0.66" or 16.8 mm from the end of the collar.
Spacing required underneath?
Make the insert hole deeper than the insert itself because the insert is melting its way into the plastic and needs space to move. If the hole is not deep enough the plastic the insert is melting on its way down has nowhere to go. In the worst case scenario plastic may seep back into the center making it difficult to put a screw in or mound around the insert at the top edge. We try to make the hole at least an additional 1/3 to 1/2 as deep as the insert.
Do these need to be cleaned?
Once heated the beautiful shiny brass will darken. That's normal. If you happen to get plastic onto the tip you may be able to clear it by wiping on a wet rag or steel or brass wool. Acetone would chemically clean it but make sure the iron is not hot when you do that!
