please help me identify this part

please help me identify these. they came with a: Folger Tech Prusa i3 kit that i bought from eBay. printer is all finished being built, i haven't calibrated it yet though. i can't find any info about these springs anywhere...

They are springs from cloths line pins. They are used as belt tensioners.

I personally wouldnt bother with them.
Tighten your belt properly and later print and fit a proper rigid tensioner.

The idea of using these belts is that they are strong, hard wearing and dont stretch.
Adding a spring makes them stretchier not tighter.
