You are buying all the assembly fasteners for all the PCB electronic boards and the rear cover from a C1 77" LG OLED TV. 

I have owned this TV since new. Everything with the TV worked 100% up till the bottom edge of the screen got damaged.

This screws do fit or interchange with other models. visual confirmation to verify the screws you need are here before making a purchase. 

DO NOT buy this if you are not sure if this is your problem or if you are not sure if this is correct for you model!
