An assortment of nylon push nuts from Hillman. Nylon push nuts have a wide flange at one end that acts as an integrated, non-spinning washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. Push nuts are meant for quick assembly by simply pushing them into place - no tools required! The push nut variants included in this assortment come in black, red, & white colors and range 3/16 thru 1/2" in diameter. Full assortments of #59032 contain six (6) refills comprised of Hillman item numbers #59033 - #59038.
