Found a tiny set screw in bondtech parts

I'm on step 32 of the e-axis assembly  https://help.prusa3d.com/guide/5-e-axis-assembly_169235 and in the bag with the bondtech parts appears to be tiny (less than 1mm?) set screw. Is this an extra set screw for the part used in step 10?  Or did something fall out of another part?

 

Thanks,

Sean

That looks like the set screw for the bondtech gear which goes on the extruder motor shaft

Same to me. There are 2 bondtech but only one of them as such a screw. 
I guess the second one is a spare part.

Yes, that should be the screw for the BondTech gear shown in step 10.

If memory serves, there is a spare screw included.

Cheers

I think it was just extra.  There was a set screw already installed in the gear, and this one floating around in the bag.

It does look like the step 10 screw that is already in the gear.  I checked that screw already in the gear didn't fall out by loosening it and then retightening it.  So it does seem like the loose screw is an extra.  I  didn't expect to have an extra and I was starting to become concerned that I broke something.  Thanks for all the replies and the help in tracking this down.

Out it in the spares bag, and remember M3 x 3mm grub scews are or toothed wheels on X and Y, and thermistor retention in the heater block, 
M3 x 2mm grub screws are for Bondtech  extruder motor hobbed gears.
