OK amigos, I need help finding a fist full of the screws that hold old school valves in place on my 6 year old Riken. You know these valves, they're the ones you hate. They don't have a one way valve and you have to hold the pump on while you screw it tight. They're white plastic held on by six screws. They're the tiniest little screws you've ever seen, like 3/16' long tops. Anyone have any or know where I can buy some?
