An assortment of zinc-plated wing nut and nylon insert lock nuts from The Hillman Group. Wing nuts offer a tool-free way to make easy hand adjustments in applications for which quick assembly or disassembly are desired. Nylon insert lock nuts are hexagonal nuts used with bolts and washers of the same material, finish, and grade. The interior nylon ring creates rotational resistance when displaced by a mating male threaded fastener, thus preventing loosening. The nylon insert also helps resist vibration and adds extra corrosion resistance. This assortment features variants ranging from #10-32 to 1/2"-20 in fine screw thread size. Full assortments of #45250 contain twelve (12) refills comprised of Hillman item numbers #603 - #608, #4341 - #4345, and #4366.
