{"product_id":"1-2-20-nylon-insert-locknut-zinc-plated","title":"1\/2-20 Nylon Insert Locknut Zinc Plated","description":"1\/2-20 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.","brand":"FMW Fasteners","offers":[{"title":"Default Title","offer_id":29021890150422,"sku":"1585242053-1739","price":0.07,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0261\/2215\/8102\/products\/media_394x_a6edf4e1-42d5-44b7-a720-7ffac0c8d33a.jpg?v=1585603094","url":"https:\/\/toolsfortitans.myshopify.com\/products\/1-2-20-nylon-insert-locknut-zinc-plated","provider":"Titan Tools","version":"1.0","type":"link"}
