A pack of 20 blue insulated fork crimp terminals. Also called cold pressed connectors, terminals, ferrules, and various other names depending on where you were raised.
Not much more to say about this, it is what it is, insert wire, use a crimping pliers to, err, crimp it, and there you go.
Hole/bolt size: 5mm
Recommended Wire Size: 1.5-2.5mm² / 16-14 AWG Cable
Recommended Maximum current: I don't have an exact specification but I think 12 to 15A maximum is a reasonable guess.
Get your crimp on.
