Nylon insert locknuts are hex nuts with a nylon-filled collar.  When a screw reaches the collar, the threads and nylon form a tight, frictional fit restricting movement of the screw when it is subjected to vibration.  Designed to be used with like-material machine screws and bolts, nylon insert locknuts can be reused more times than a two-way reversible nut, however, nylon will begin to deteriorate at temperatures of 150°-350°F so they are not recommended for high temperature service.  Typical hardness will reach a maximum of Rockwell C28.  Nuts are manufactured to meet a proof load of 90,000 psi minimum.\u003c\/p\u003e","brand":"FMW Fasteners","offers":[{"title":"Default Title","offer_id":42530590621776,"sku":"1721008","price":2.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0242\/9940\/5392\/files\/media_f15e51cb-742f-44d8-98fc-5d852e9d44e5.jpg?v=1781189989","url":"https:\/\/store.zoellerpumps.co.za\/products\/1-4-28-nylon-insert-locknut-zinc-plated","provider":"store.water-services.us","version":"1.0","type":"link"}
