2 awg ferrules

[e67]

I installed a anl fuse and battery disconnect today. The fuse takes raw wire into its ends or ferrules.It is one of those for auto stereo installs I think. But its a tight fit with just the raw wire. 2 awg copper.
Is it ok or should I get some ferrules for it?? And where would you source 2 awg ferrules?? I didn't see any on ebay..

Amazon has 2 awg ferrules. I prefer to use ferrules on all fine strand wire.
Edit: THHN does not need ferrules... if the wire is flexible, then use ferrules, if its stiff, then no ferrules
