{"product_id":"3-4-16-nylon-insert-locknut-zinc-plated","title":"3\/4-16 Nylon Insert Locknut Zinc Plated","description":"3\/4-16 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":29021891067926,"sku":"1585242033-1733","price":1.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0261\/2215\/8102\/products\/media_394x_b215226d-9cf9-4330-8317-71940b1a0643.jpg?v=1585603101","url":"https:\/\/toolsfortitans.myshopify.com\/products\/3-4-16-nylon-insert-locknut-zinc-plated","provider":"Titan Tools","version":"1.0","type":"link"}
