Perfect for my expensive glass top desk and plastic wheels, three of which broke. They are much stronger and perfect for those hard to reach 10mm lugs that I need. I've tried Home Depot, Ace, Lowes etc but none other than Revain had one with a 10mm threaded bolt. Thanks to Revane, my table is fully fixed, articulated, and level again, and is missing the 2Γ4 pieces I had to use to support the table after the original three wheels broke.
