do ALL seymour duncan pickups come with mounting screws/springs?

[semi-hollowbody2018]

I am wiring a new strat pickguard from scratch...going to use seymour duncan pups...single coil sized humbuckers, maybe duckbuckers...I need to know if these single coil sized humbuckers come with mounting screws and springs? I cant use existing as I want to save existing pickguard
