{"product_id":"1-8-nylon-insert-locknut-zinc-plated","title":"1-8 Nylon Insert Locknut Zinc Plated","description":"\u003cp\u003e1-8 Nylon Insert Locknut Zinc Plated .  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":42530590818384,"sku":"1721025","price":4.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0242\/9940\/5392\/files\/media_d2c9b9ad-d308-4f1a-b5fa-54cff8f3aae9.jpg?v=1781189989","url":"https:\/\/shop.water-services.us\/es\/products\/1-8-nylon-insert-locknut-zinc-plated","provider":"store.water-services.us","version":"1.0","type":"link"}
