ARP Chrome Moly Steel Nut

ARP Chrome Moly Steel Nuts are high-strength fasteners made for engine, driveline and chassis assemblies where standard hardware isn't strong enough. They are also sold as chromoly nuts, 8740 chrome moly nuts or high-performance fastener nuts. They pair with ARP studs and bolts to give a secure, consistent clamp load in demanding street, racing and performance builds.

Key Features:

• Chrome moly alloy steel construction gives high tensile strength and good fatigue resistance.
• Heat-treated for strength and durability under high load, heat and vibration.
• Precision-machined threads help the nut seat evenly and keep clamp load accurate when tightened to the specified torque.
• Made in the USA under ARP's quality control standards, with ARP's well-known focus on fastener quality and consistency.

ARP is a trusted name in performance fasteners, and its hardware is used widely in motorsports and high-horsepower engine builds. Follow ARP's recommended torque specifications and lubricant guidelines during installation to get the correct clamping force.
