Mounting hardware for water block to CPU

[RIRed48]

The mounting hardware I have with the EK Evo nickel water block has me confused.

There are two 4 piece sets of mounting screws in the packet. One set is called 'M4 mounting studs' and is for an LGA2011 CPU, and the other set is called 'M4 threaded thumb screws' which are for the LGA 1151 (what I have).... BUT, it doesn't tell you which is for what CPU... Both sets look much alike, but one set of screws is larger/longer than the other, but they both fit through the 4 holes in the motherboard. So, I don't know which set of screws to use....

HELP, please...

The new system build listed below.

You said you have an LGA 1151 socket and there is a package of hardware labeled as LGA 1151. I'm not sure what your question is? Maybe I'm not reading it right?

Sorry, they were not labeled. I figured it out. All set, thanks.
