Help with new computer

Hello guys, i just built my first pc last night and when i tried to install the motherboard, 4 of the screws went all the way into 4 built-in standoffs without issue but i had to add 2 brass standoffs at the bottom for the mobo and the screws couldn't go all the way into those brass standoff. What should i do? Can i just leave them like that? They're not completely in but not loose either like half way in so it looks pretty secured but i'm not sure if it's going to fall off when i install the gtx 750ti later today.

This is the mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813157512

This is the case http://www.amazon.com/gp/product/B00J0NZ6PW?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00
Thank you

Your case should come with all the screws and standoffs. If you're short, I'd contact the seller or conversely you could buy some additional standoffs/screws. That motherboard requires 6 standoffs and screws. I wouldn't leave it like that
