7/16 Neckdown Stud - 5.000 Long 3/8 Head

The ARP 7/16 Neckdown Stud – 5.000 Long with 3/8 Head is a precision-engineered fastener designed for high-performance engine and drivetrain assembly applications where critical load-bearing reliability is required. This neckdown stud features broached construction to ensure accurate thread engagement and uniform clamping force, making it an essential component for builders working with chromoly-construction fastening systems in racing, restoration, and high-output engine builds.

The stud accommodates dual thread specifications—3/8-24 and 7/16-14—allowing flexibility in assembly configurations where mixed fastener sizes are required within a single component interface. At 5 inches long with a 3/8-inch head diameter, this fastener is sized for applications requiring substantial engagement length without excessive protrusion. The black oxide finish provides corrosion resistance and reduces galling during installation, critical factors in engine environments where repeated assembly and disassembly cycles are common. Broached studs offer superior concentricity compared to rolled threads, translating to more consistent preload values across multiple fastening points.

This stud is specified for engine block, cylinder head, and rotating assembly fastening where precise thread control and load distribution are non-negotiable. Builders selecting ARP neckdown studs typically operate in competitive and professional-grade engine programs where fastener consistency directly impacts engine durability and performance. Sold individually, this fastener integrates into broader stud kits or serves as a replacement component in existing engine assemblies, offering the specification consistency that manufacturers and engine builders rely on for sustained high-RPM operation.
