They don't make the screws out of nickel. They plate them with it. Often to denote neutral from hot screws. The hots are left brass or plated brass. Nickel plate looks like chrome. It sounds bright IMO. Some outlets have brass screws but the backing plate they go into are steel. You find this on outlets with both side and back wire attach points. Try to find a all brass outlet.

Thanx for the quick reply. I was surprised to see so many outlets with chrome plates but none with brass screws on both sides. I'd like to remove the nickel screws and use one of the two brass screws from hot but they are not removable. Did you remove them by force or there's a better way?
I have a special way to remove them from the outlets I use, but it won't work with other brands. The screws are self tapping and installed by machine. They have a stop that you have encountered. just continue to back them out. You will need to firmly hold the outlet and use a big screw driver. Good Luck
Mike, Thanx to your instruction, I've successfully backed out the screws with a big screw driver. I did it on a Hubbell 5252 which appeared to be whole brass with exception of neutral nickel screws. But guess what I've just discovered, the inner contact plate which was not visible before I removed the screws, is apparently nickel. I wanted to make sure it's made of brass so I used a small magnet-tipped screw driver to stick inside the screw hole to see if the inner plate would be attracted to the magnet.Bad news! The plate sticks up to my magnet-tipped screw driver, that means it's made of steel! Steel is said to be the worst signal conductor for audio and now I wonder if changing the screws would do any good. This makes me curious about all the rest of outlets out there including Hubbell 5262, 5362, P&S 5262A, 5362A. Are these so called full-brass outlets have no steel equipped whatsoever? Has anyone checked on this before?
Yes, most of the backing plates are made from steel.
the 5262 Hubbell I have is all brass but they might have changed to steel. P&S did with screws on a bunch of their spec grade outlets. I can only guess that the cost of brass has become a factor.
I checked Hubbell's spec sheet. Model 5252 does have clamp plate listed as made of steel. That's a real pity since all other parts are made of brass. The 5262's clamp plate is shown as made of brass and since all manufacturers have jacked up their prices already, I don't see how it's proper for Hubbell to alter the specs for their products. It looks like Hubbell 5262 is full-brass afterall. Which makes it perhaps the best buy outlet available. Thanx Mike.
