Grade 5 Zinc-Plated Bolts with Nuts, Pair","description":"\u003cp\u003eThe Tie Down Engineering Fluted Shackle Bolt (86250) is a 3\/8 in. X 3 in. Grade 5 zinc-plated bolt set designed for use with trailer spring hanger brackets and equalizers. Each bolt features a fluted shank, a design engineered to prevent the bolt from turning inside the hanger bracket during installation or use. A bolt that spins in place can wear out the hanger bracket over time, so the fluting keeps the bolt fixed while the nut is tightened, protecting the bracket and helping the connection stay secure.\u003c\/p\u003e\u003cp\u003eBuilt from Grade 5 steel with a zinc-plated finish, this bolt set resists corrosion in the wet, road-splash, and marine-adjacent environments common to boat trailer axles. The 86250 is sold as a pair, with each bolt shipping alongside a matching nut, giving you both fasteners needed for a spring hanger bracket or equalizer replacement in one package. This makes it a straightforward maintenance or upgrade part for trailer owners replacing worn, rusted, or damaged shackle hardware.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tie Down Engineering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 86250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Fluted Shackle Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size:\u003c\/strong\u003e 3\/8 in.
