iExcell 25 Pcs 12.9 Grade M5 x 60/65/70/75/80 mm Thread Pitch 0.8 mm Alloy Steel Hex Socket Head Cap Screws Bolts Assortment Kit, Black Oxide Finish

If you’re buying these to do the gimbal spring mod on the Flysky NV14 Nirvana transmitter, they will work but with a couple caveats. First the thread pitch is different, but you’re also screwing into plastic so this screw will cut it’s own threads. Take it slowly and it shouldn’t damage the spring adjuster. This works out great in the end because these screws have a finer pitch, so they’ll let you make finer tension adjustments on the springs. The second caveat is that the screw heads are a LOT bigger than the screws you remove, so they will rub slightly on the edge of the circuit board on the backs of the gimbals. I used a small diamond file that came with one of my mini quad frames to file the edge of the board slightly so the screw head would clear it (about 1/32”). This mod makes a huge difference in stick feel, and now I can throttle up without turning, and turn without throttling.

These appear to be higher quality than the other ones I purchased here. sockets fit on the allen wrench nice and tight, and they are the same length as the ones they are replacing. Nice and dark black, not dark brown like some. Will buy again!

These kits should also contain longer screws and female/female spacers for more build options.

They work good for plastic screws..
