Installing Rack

I am so so close to having this bike rack fixed onto my bike… my problem now is that the bottom bracket for the rack is straight and would need to be bend to go over the rim brakes.

my question also what are these screws called that go inside the brake holes? If i were to remove the front brake, i would like to purchase similar type of screws to be hidden into the hole.

i am most likely going to have a bike shop bend it. but i was excited to finally have all the hardware to install the rack
