The ARP 9/16 Stud - 5.870 Long Broached is a precision fastener engineered for high-performance engine assembly and critical mechanical applications. This chromoly stud is designed for builders and technicians who demand reliability under extreme stress, whether in automotive performance builds, industrial machinery, or precision equipment restoration. The broached construction ensures consistent thread engagement and superior load distribution compared to rolled-thread alternatives.
Manufactured from chromoly steel and finished in black oxide coating, the 9/16 Stud - 5.870 Long Broached delivers corrosion resistance and durability in demanding environments. The broached thread design—available in both 9/16-12 and 9/16-18 pitch options—eliminates stress concentrations inherent to rolled threads, reducing fatigue failure risk under cyclic loading. At 5.87 inches long, this stud accommodates multi-layer assemblies common in engine heads, transmission casings, and structural fastening applications where precise length and thread integrity are non-negotiable. The black oxide surface treatment protects against rust while maintaining a professional, factory appearance.
Technicians, engine builders, and precision machinists rely on ARP studs for applications requiring universal compatibility across multiple platforms. This stud suits engine block head fastening, turbo mounting, and any assembly where vibration resistance and thread longevity define success. Whether you're assembling a high-horsepower engine, rebuilding machinery, or restoring vintage equipment, the broached construction and chromoly composition ensure that fastening integrity remains consistent across thousands of thermal and mechanical cycles. Each stud is sold individually, allowing builders to replace or upgrade fasteners as needed.
