ARP 200-8630 Serrated Flange Hex Nuts Set Engine Hardware - 10-Piece

ARP's serrated flange hex nuts are precision-engineered fasteners designed for high-performance engine applications. This 10-piece set features integrated serrated flanges that provide superior grip and resistance to loosening under vibration and thermal cycling.

Key Features:

• Premium-quality steel construction with cadmium plating for corrosion resistance
• Rated at 150,000 psi tensile strength for reliable clamping force
• Serrated flange design eliminates the need for separate lock washers
• Ideal for carburetor studs, valve covers, front covers, oil pans, and windage trays
• Manufactured to ARP's exacting quality standards

The flanged collar distributes load evenly across the mounting surface while the serrations bite into the material to prevent rotation. These general-purpose fasteners are essential hardware for engine builders and performance enthusiasts who demand reliability and consistency in their builds.
