    Not sure where to buy 24-pin headers. I usually buy a bunch of 40-pin female headers from Amazon (example: https://www.amazon.com/Qunqi-2-54mm-...%2C157&sr=8-5_) and cut them down to size. Usually I cut them with a pair of cutters on the 25th pin and then just file it down to get rid of the excess plastic

    Ok. That kind of changes the approach, doesn't it. Dont't blame you. In the US I usually got things like that from a peconnectors - https://www.peconnectors.com/female-...-.100/hws6558/.

    Have you tried digikey or mouser?

    PJRC has them, but only the normal / short pins

    https://www.pjrc.com/store/socket_24x1.html

    For the long pins to make stackable boards, get them from Sparkfun.

    Note for the stacking headers for the Teensy LC, 3.2, or 4.0 go with the Adafruit ItsyBitsy/Teensy headers and not the Sparkfun headers:


    The Adafruit headers have 2 sets of 14 pin headers and 1 set of 5 pin header, while the Sparkfun headers have 2 sets of 13 pin headers and 1 set of 7 pin header. If you are putting the headers on the audio or octows2811 shields, the 14 pin headers are needed, because those two boards don't have the 5 pins in the back row.

    I'm not sure those are the parts I found by stepping through the DigiKey search process, but I'm strongly biased toward them. It was DigiKey that made it possible for me to start a small board production facility early in this century.
    I used a lot of SAMTEC connectors because they offered a Low-Insertion-Force version of the connectors I needed. Seating a plug-in board with 100+ pins was much easier with the LIF versions of the headers. I'm still pulling leftover SAMTEC connectors from my bins for this year's Teensy projects. My orders soon got to the point where I went directly to SAMTEC. They had online ordering with credit card payment before a lot of other companies. Even today, my kids and in-laws are used to seeing Christmas gifts arriving in the conveniently-sized SAMTEC boxes.

    Back in the day, a guiding principle of my hardware designs was "If it's not on DigiKey, don't put it into the hardware design." It's sort of the small hardware shop version of "No one ever got fired for recommending IBM".
    When I go looking in my parts bins for something for a current Teensy project, there's about a 95% probability that I'll find it with a DigiKey label. A more efficient large company would be upset with my inventory management, but in my niche market, late delivery was always more of a problem than having too many parts in the bins. (If you've got spares in the bin, you can discard parts that got soldered on backwards. The rework costs would exceed the parts cost--as long as you had parts in the bin!)

    P.S. If you don't know about Chip-Quik, Google is your friend!

    Btw you can buy it with headers already soldered:

    Ken at protosupplies.com 24+pin+header has some normal and more expensive great quality low profile versions in 24 pin lengths.

    Some of us used the recommended low profile ones and I needed more - Ken ordered a bunch and has them in stock.

    If you wanted stackable headers, Sparkfun sells a pair of 24-pin headers + a 5 pin header:
