Correct measurement matters because U-bolts are not universal. The diameter, thread pitch, inside width, leg length, and bend shape all need to match the trailer application.\u003c\/p\u003e\n\u003cp\u003eThe zinc-plated finish helps reduce corrosion in marine trailer use. Zinc plating acts as a sacrificial coating, meaning the zinc helps corrode before the underlying steel. This makes zinc-plated U-bolts a practical factory-style hardware choice for boat trailers exposed to road spray, freshwater, saltwater, humidity, and ramp use.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-size: 15px; margin: 20px 0;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 12px 14px; background: #12344d; color: #ffffff; font-size: 18px; border: 1px solid #d9e2e8;\" colspan=\"2\"\u003eProduct Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32%; padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003ePart Number:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003e290-027532\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003ePart Type:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eTrailer U-bolt \/ U-bolt hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eThread Size:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003e1\/2\"-13 coarse thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eInside Width:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003e3\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eLength:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003e5-3\/4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eMaterial \/ Finish:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eZinc-plated steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eColor:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eZinc \/ silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eFits:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eCompatible EZ Loader trailer applications requiring a 1\/2\"-13 x 3\" x 5-3\/4\" zinc-plated U-bolt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eApplication Type:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eBoat trailer hardware, bunk hardware, bracket hardware, roller hardware, suspension-related hardware, and frame-mounted fastening applications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eFunction:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eHelps clamp or secure compatible trailer components where a 3\" inside-width U-bolt with 5-3\/4\" leg length is required.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eWhy Buyers Like This Part:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eFactory-style EZ Loader hardware, zinc-plated finish, common 1\/2\"-13 thread, wider 3\" inside width, useful for replacing rusted, bent, missing, or damaged U-bolts.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px 14px; font-weight: bold; border: 1px solid #d9e2e8; background: #eaf3f8;\"\u003eImportant Fitment Note:\u003c\/td\u003e\n\u003ctd style=\"padding: 12px 14px; border: 1px solid #d9e2e8;\"\u003eConfirm thread size, inside width, leg length, and trailer application before ordering.
