Secure your truck's frame and chassis components with the Grade 8 Flange Head Cap Screws, available in a range of lengths, bolt diameters, and thread pitches to suit different repair and maintenance needs. Made from steel, these flange bolts are offered in coarse- and fine-thread options, including 1/2-inch and 5/8-inch diameters with various lengths. The integrated flange head provides a built-in bearing surface for install. These Grade 8 fasteners are aftermarket replacement parts, sold individually, with select options replacing OE numbers such as D85020428, 414052C1, and 8397032. Each screw includes a warranty against defects in workmanship and materials from the date of purchase. Designed for universal truck applications, these cap screws are a practical choice when the selected specifications match your equipment. Please verify bolt diameter, length, and thread pitch before ordering to ensure the correct fit. This is a special-order item, so orders cannot be canceled and the product is non-returnable.
