ProTek RC 4-40 x 1" "High Strength" Flat Head Screws (10)
Figured I'd mention that these make a perfect and far, far better screw to use for the stock plastic XR10 beadlocks. Even if you've already used the junk ones that came with the kit, these will still work without fail. They take a 1/16" hex wrench.
