X 3-13\/16 in., Zinc Plated, Part 86222","description":"\u003cp\u003eThe Tie Down Engineering 86222 is a square-bend U-bolt built for mounting trailer springs, brackets, and axle hardware to 1-1\/2 inch square frame tubing. It is manufactured with a zinc-plated finish that resists corrosion during everyday road and marine-trailer exposure, keeping the threads and bend clean for reliable installation and future removal. The U-bolt has a square shape to match flat-sided frame stock, with 1\/2 in.-13 threaded ends sized to accept standard 1\/2 inch nuts and washers. Overall it measures 1\/2 in. X 3-1\/16 in. X 3-13\/16 in., a compact size intended for spring plates, roller brackets, and similar square-tube mounting points on boat trailers and utility trailers. The finish is gray zinc plating over the fastener body, with a right-hand thread standard to U.S. Hardware. This listing is for a single U-bolt (each); Tie Down also offers this same 1-1\/2 inch square size as a matched pair under a different part number, and a round-shape version for round frame tubing, for buyers who need an alternate configuration. Because it is a precision-bent mounting fastener rather than a universal bolt, matching the frame size and shape (square vs. Round) is important to get a proper, snug fit without stressing the bend.\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 86222\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 1-1\/2 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/2 in.-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 3-1\/16 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3-13\/16 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Zinc Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e U-Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style:\u003c\/strong\u003e Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade:\u003c\/strong\u003e Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 (Each)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 081628862225\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eSized for 1-1\/2 inch square trailer frame or axle tubing, with 1\/2 in.-13 threaded ends for securing spring plates, roller brackets, and similar square-mount hardware.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size frame does the Tie Down 86222 U-bolt fit?\u003c\/strong\u003e It is sized for 1-1\/2 inch square trailer frame or axle tubing, matching the square bend of part 86222.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this U-bolt sold as a single piece or a pair?\u003c\/strong\u003e Part 86222 is sold individually (each).
