Drone building

I only needed a couple - so i have a lot of extras, but the price was so good that I could not pass it up. I only wish the nuts were nylon locking stainless nuts - those exist, but not in these kits. I buy them separately, and have a lot of "regular" nuts that I will never use.

I bought these as screws I can use with my Creality printers and the sizes and lengths have really helped out. I've printed some mods and having the longer screw really made attaching them easy when the factory screws were not long enough. I'd recommend getting these if you're into stuff like that so you have a good selection to work with.

I use these to mount my flight controllers for drones. Need a longer length so the FC and the 4-in-1 ESC wasn't touching each other. Worked great and exactly what I needed.
