Nylon Insert Locknuts

Nylon Insert Locknuts

Nylon Insert Locknuts, also known as Stop Nuts, are available in steel with a zinc, black oxide, black zinc and yellow zinc finish; and in 316 and 18-8 stainless steel, with an optional black oxide finish. Offering a wide array of styles, nylon insert locknuts feature a nylon filled collar at the back end which restricts movement once a threaded fastener is installed.
