Friends:
It’s a clearance bolt hole. Drill it out and install a new one.

There's no need to hit the bolt, just press it out with a pulley puller set
for two legs.

I personally would try to soak the offending post in a solution of baking
soda or some other corrosion remover for a while and then gently tap the
bolt on both sides. Continuing to do this will eventually loosen the
bolt.This IS a thru bolt not something that is threaded. certainly one can
drill it out using the step approach 1/8 " then 3/16 then 1/4 till you
get to 5/16. Gently tapping or drilling you should find this removal
easier then you thought. Tump

The EZ out is for unscrewing a threaded connection, I've spent a bunch of
time with those only to have the EZ out break off in there too. Then
you've got a real mess of hardened tool steel.
I would first drill several small 1/8" holes in the lead around the
circumference of the bolt. Then, I think tapping or pressing it out is the
way. The wheel puller would probably work. You'll end up with an
enlarged hole that you can either use a bigger bolt, or washers to deal
with.
I agree some of the hardware that comes with cheaper L 16s, is inferior.
I've had plenty of those square heads come off with minimal torque.

Yup, id pre-drill and use an ez-out, or use a flaring tool as a small press
and drive it out.

Greetings,
Do any of you battery gurus have a suggestion for a method of removing a
bolt remnant that is corroded into a flag terminal. Both sides snapped off
flush with the flag. I was thinking try to drill it out or maybe a small
gear pulling tool? I will never again use the non stainless hardware
supplied by the manufacturer...
Picture attached for reference.
Thanks!
