Regular hex nuts can easily backing off, putting your axle alignment and safety at risk. This heavy-duty 9\/16\"-18 hex locknut is engineered with a specialized locking mechanism (either nylon insert or a flared-lip lock style) to grab onto the shackle bolt and stay tight over thousands of miles.\u003c\/p\u003e\n\u003cp\u003eMade from high-tensile, heat-treated steel, this nut is highly resistant to thread stripping and rust. Perfect for maintaining or rebuilding utility trailers, flatbeds, or car haulers with 7K axle slipper suspension. Its reversible design allows you to easily start threading it onto the bolt from either side during a fast suspension swap-out.\u003c\/p\u003e","brand":"RunningGearParts.com","offers":[{"title":"Pack of 8","offer_id":44271716237415,"sku":"SP-HW-FPN916L-M","price":20.49,"currency_code":"USD","in_stock":true},{"title":"Pack of 16","offer_id":44271716270183,"sku":"SP-HW-FPN916L-M","price":36.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8617\/5079\/files\/RGPFPN916L.png?v=1784752672","url":"https:\/\/www.runninggearparts.com\/products\/9-16-18-trailer-shackle-locknut","provider":"RunningGearParts.com","version":"1.0","type":"link"}
