Worried about my headstock (images applied)

Thanks, @C_Becker - I just added all four of those to the setup sticky post.

I just bought new strings and normally I cut them down a bit before I attach them to the tuning pegs but I didn't for whatever reason this time and the thing near the bottom near the neck got bent (sorry, don't know what it's called in english)

I've always found it to be a bit too close and I believe it has been the reason why the B string is so hard to tune, I don't really know what it's there for. My other basses goes directly to the tuning pegs. My questions are:

Should I turn it in to repair to be changed?
What is its use? Is it necessary?
Can it be changed to a different mechanic?

Maybe it's me?

What exactly is that string retainer supposed to accomplish?

Is it stock?

It appears the strings would break straight without the retainer?

The retainer also should have some bushings as the mounting screws are either going to break, bend or elongate the holes, which appear to be happening. The high and low strings will fun on the threads of the screw, with no bushing, not good.

Your windings are also somewhat untidy, and no doubt contributing to the tuning issue.

String retainers are commonly used on headstocks with 6 in line tuners.
They put some pressure on the D and G string, where the tuner is farther away from the nut, thus reducing the break angle. Usually Fender uses a round disc-shaped retainer, not sure if this one came stock.
