ARP 100-1108 Header Bolt Kit Hex Head 3/8-16 x 1.000 (16-Piece)

ARP's 100-1108 header bolt kit provides premium-grade fasteners engineered specifically for exhaust header installation. This 16-piece kit features hex head bolts manufactured from high-strength material designed to withstand the extreme heat and vibration of exhaust applications.

Key Features:

• Hex head design for easy installation with standard sockets
• 16 pieces included for complete header installation
• Nominally rated at 170,000 psi tensile strength—substantially stronger than Grade 8 hardware
• Black oxide finish provides corrosion resistance and professional appearance
• Chrome moly construction for superior durability under high-temperature conditions
• Precision-manufactured threads ensure reliable torque retention

ARP's header bolts are engineered to maintain clamping force in demanding environments where standard fasteners often fail. The chrome moly material resists thermal expansion and contraction cycles that can cause conventional bolts to loosen over time. Each bolt is manufactured to exacting tolerances to ensure proper fit and maximum reliability.

Ideal for performance and racing applications where header security is critical. Compatible with most small block and big block engine configurations requiring 3/8-16 thread header bolts.
