As the bolt threads through the insert, the nylon compresses around the thread and creates prevailing torque that resists loosening under vibration and dynamic loads. No separate lock washer is required.\u003c\/p\u003e\n    \u003cp\u003eThe low carbon steel body handles the structural load; the nylon insert handles the locking. These nuts can be reused several times before the nylon loses its grip — but for critical applications, single-use is the recommended practice.\u003c\/p\u003e\n    \u003cp\u003eOne important limitation: nylon softens above approximately 250°F. For high-temperature applications such as exhaust hardware or engine components, use all-metal prevailing torque nuts instead. For general shop, equipment, and chassis applications that stay within normal temperature ranges, nylon-insert lock nuts are the standard choice.\u003c\/p\u003e\n    \u003cp\u003eClear zinc finish provides corrosion resistance for shop storage and typical indoor or protected outdoor use.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n  \u003csummary\u003eShipping \u0026amp; Ordering\u003c\/summary\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n\u003cstrong\u003eShips within 1–2 business days\u003c\/strong\u003e from our warehouse\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eVolume pricing available\u003c\/strong\u003e — save up to 20% when ordering 3 or more kits\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eB2B accounts:\u003c\/strong\u003e Fleet managers, facilities teams, and machine shops can apply for a business account with custom pricing and a dedicated rep — \u003ca href=\"\/pages\/contact-us\"\u003econtact us to get started\u003c\/a\u003e\n\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003c\/div\u003e","brand":"NutsandBolts.com","offers":[{"title":"Default Title","offer_id":48550632915185,"sku":"ASSTNLN6C","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0946\/2001\/files\/Photo-1_ASSTNLN6C.jpg?v=1786652348","url":"https:\/\/shopmanu.com\/products\/190-piece-lock-nut-assortment-starter-kit-low-carbon-nylon","provider":"Manu","version":"1.0","type":"link"}
