If you're dealing with a leaky sink strainer, this Danco replacement nut is exactly what you need! It measures 2-1/2 inches OD by 1-13/16 inches ID with a 13/32 inch thickness - perfect standard size for most kitchen sinks. The metal construction feels solid and durable - not that cheap plastic that cracks easily. Installation is straightforward - just remove your old nut and thread this one on to create a tight seal against your sink. No more annoying drips that can damage your cabinets or floor over time. The universal design works with most strainer assemblies, which is super convenient. Much better quality than the original part in many cases. I've used these for multiple sink repairs and they always fit perfectly. The threading is clean and smooth - no cross-threading issues. Prevents water from seeping through where the strainer meets the sink basin. Works for both kitchen and bar sink installations. The price is reasonable compared to buying a whole new strainer kit. Whether you're a DIY homeowner or professional plumber, this little part solves a common plumbing problem. Definitely one of those simple repairs that saves you from calling a plumber. Keep a couple on hand for future projects - you'll be glad you did when a sink starts leaking unexpectedly.
