Description

Built for demanding mechanical and structural applications, this 1/2"-13 x 1-1/2" Grade 8 flange bolt SAE J429 delivers superior strength, durability, and vibration resistance in a single fastener. Manufactured from hardened alloy steel and heat-treated to Grade 8 specifications, it offers significantly higher tensile and yield strength than standard hardware. The integrated flange acts as a built-in washer, distributing load evenly across the surface and helping resist loosening under vibration—ideal for automotive, industrial, agricultural, and equipment repair applications. A zinc plating provides corrosion resistance for indoor and light outdoor use while maintaining clean, professional appearance. Common Uses: Automotive suspension and chassis work, machinery assembly, equipment mounting, structural repairs, and heavy-duty fabrication.
