Moroso 38710 Grade 8 Header Bolts with Black Oxide Finish

The Moroso 38710 Header Bolts are engineered for high-performance engine applications where strength and durability are critical. These Grade 8 fasteners provide superior clamping force to maintain a secure, leak-free seal between exhaust headers and cylinder heads, even under extreme heat and vibration conditions.

Key Features:

• Grade 8 strength rating for maximum tensile strength and reliability
• Heat treated construction for enhanced durability in high-temperature exhaust environments
• Black oxide finish provides corrosion resistance and a professional appearance
• 7/16" hex head design allows for easy installation and removal with standard tools
• Precision-manufactured threads ensure consistent torque values and proper clamping force

Moroso header bolts are designed to withstand the thermal cycling and vibration inherent in performance exhaust systems. The black oxide coating helps prevent rust and galling while maintaining dimensional stability. These bolts are ideal for street performance, racing, and custom engine builds where header retention is essential for optimal exhaust system performance.
