This appears to be an automotive fuse block. If so, this will probably not end well…
Nahh, it’s OK.
Needed more amps for the new 3Kw subwoofer amps for the boom booms.

In an emergency, that will work. NOOOOO.
Yeah I see multiple problems.
One is not tight, one is in backwards, one is too short and he should have used metric bolts.
I tole cousin Billy-Bob to put the hood back on his truck and quit leavin it off, the rain gets things all wet and will riunt em.
Eh, no biggie. The wiring itself will now act the fuse. 
A friend and I once worked on a car that kept popping the brake light fuse. The owner told us he just kept replacing it until he ran out of 20 Amp fuses. Then he moved on to a couple handfuls of 30 and 40 Amp ones. 
He only asked us for help when the turn signals began activating the wipers, and the headlights only worked when the rear defroster was on.
One leg of the wiring harness behind the dash had a bundle of about 20 wires with scorch marks and melted insulation in dozens of spots within a 24” run. There were countless bridges and some areas had 5 or more wires completely melted together.
The car wasn’t worth the cost of replacing the harness, so out of pity we got the basics working and told the owner to start shopping for a new ride.
That’s a spare bolt holder on an old harley motorsickle—they tend to vibrate quite a bit and shake your nuts and bolts loose.
i once had a ’57 sportster that lost the oil tank bolts and dumped it’s load in my boots.
That’s not a Fuse —- This is a Fuse
I don’t have the link and can’t find it with a short search, but I have seen an arc flash video that illustrates why in a high voltage, high amperage DC system one should never pull a fuse that is energized. ( such what might be found in a solar panel array with panels connected in a series/parallel configuration like ours). A greater flame arc than what that video resulted. The video was made using a test dummy. Serios potential for serious injuries.
w0w… THAT “IS” A FUSE!! 
IF indeed the OP is an operational fuse block & not just being used as spare bolt holder/storage… there is a large problem. 
Haha so funny. Next time if the “fuse” burns out, just use a piece or rebar.
Forget the bolts. Use .22LRs as fuses and go for the Darwin Award!
apparently they are large diodes
or polarized bolts.
(actually it doesn;t look connected to anything
and that galvanized finish, hardly conducts at all)
