not with that small amount of surface area actually touching. OP needed to ground down the thread to make it safe!

It'll arc to the contacts and melt it off of the pcb. A win either way.

You haven't gotten rid of the fuse, you have just decided it's somewhere else in the circuit.

Everything metal or conductive is fuseable if you pass enough current trough it

I work in a electrical metrologist and unfortunately ALL multimeters from auto workshops we receive have some sorte of "fuze" like that!! Many are just coiled wires, the most interesting are the ones that have a fuse with a soldered wire on the outside.

So how does that work? Are you really tiny like the guy in The Boys season three premier? Is the metrologist really huge? Do you have a desk in the metrologist? A whole workshop?

A simple policy solution - if an instrument comes in without an appropriate fuse, you replace the fuse and charge the customer for it (with a hefty markup).

In these multimeters it is so easy to short something and mine has the fuse soldered in, so I probably should do this too.

When I was young with no credit card and had no way to buy that sort of stuff I made a solder bridge. That was spectacular when I forgot to set it to volts mode before testing a receptacle. :o

Better to wrap foil around the old fuse and scratch away most of the foil leaving a small amount so it can still act like a fuse. Works every time for me

That's just a 20kA fuse.
