Man get that garbage out of my thread. Thats about to get clown nuked by the sucka patrol. Thats not an F1 holdown, that a piece of dense foam with 5 holes in it lol.

Avoid knockoffs kids.. and ALWAYS buy genuine F1 replacement parts!
Here is the real next gen F1 holdown which now supports all previous sockets as well as 1156 now and ships with every new F1 starting next week.
