ARP Metric Nuts Engine Hardware

ARP metric nuts are high-strength engine fasteners built for performance, racing, and heavy-duty applications. They are designed to be used with ARP studs and bolts. They give a secure, consistent clamping load where standard hardware can stretch, loosen, or fail under high cylinder pressure, RPM, and vibration.

Key Features:

• Premium materials: Made from high-strength alloy steels selected for strength and fatigue resistance.
• Precision manufacturing: Machined to tight tolerances, with threads that give accurate torque readings and even clamp load.
• Made in the USA: ARP manufactures its fasteners in its own facility under strict quality control.
• Metric thread design: Suited to the many import and domestic engines that use metric fasteners.
• Durability: Resists loosening and fatigue in demanding street, strip, and track use.

ARP has a long-standing reputation among engine builders and racers for fasteners that hold up under demanding conditions. Choose the nut that matches your stud or bolt thread and application for a dependable, long-lasting assembly.
