Looking for factory screws for mounting hardware drivers in Monitor 10's, SDA2 and CRS cabinets , or the screw specs will do also . Iam redoing a bunch of units and would like to use new mounting screws vs current rusted and or replace missing ones . ~ Long and short of it ... the ones that came with the units were nicely and neatly put away , but ..... some how the whole bunch just happened to disappear some time over the last holidays (putting it nicely) . So I need a whole bunch of these little black beauties (again or the specs of said screws) Seems there were all about the same or possible only two sizes between the above mentioned units . ~ Thx for the help , my little clan of Polks also thank you !

    I can only speak for my 7Bs but what Polk used was a #8 x 3/4" Phillips Pan Head Black Oxide Sheet Metal Screw (fully threaded to head). Parts Express sells one that is a coarse/deep thread version. Root diameter is smaller and helix angle is greater. They work fine for new holes which is what I used them for on my Passive Radiator to go from 4 holes to 8. I always make sure I put them back in the same places to not mix up the types.

    I've found identical screws (in my case, for 6500's) at the hardware store. That said, hurricane nuts and machine screws are superior in terms of sonics (attack and slam), and they don't strip out over time (removing/replacing drivers in the process of upgrades). They do involve some detailed work...

    Yes, maybe those screws disappeared for a reason lol. Time to upgrade? Rob's semi rings would be my recommendation.
