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":42530595209296,"sku":"1721018","price":11.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0242\/9940\/5392\/files\/media_61bdf180-80b8-400f-8f8e-a169a49270f8.jpg?v=1781190005","url":"https:\/\/store.zoellerpumps.co.za\/af\/products\/5-8-11-nylon-insert-locknut-zinc-plated","provider":"store.water-services.us","version":"1.0","type":"link"}
