3/8 Stud - 2.160 Long Broached

The 3/8 stud - 2.160 long broached from ARP is a precision fastening component engineered for demanding engine and drivetrain applications where reliability and load capacity are non-negotiable. Designed for builders, mechanics, and performance enthusiasts who require fasteners that can withstand extreme pressures and vibration, this chromoly stud delivers the dependable clamping force needed in critical assembly scenarios. Whether you're building a high-horsepower engine, reinforcing transmission mounts, or securing suspension components, this broached stud provides the foundation for a secure connection that lasts.

Manufactured from chromoly steel and finished with black oxide coating, the 3/8 stud offers superior tensile strength compared to standard mild steel fasteners while resisting corrosion and wear. The broached design ensures precise thread engagement with both 3/8-16 and 3/8-24 thread pitches, eliminating binding and providing consistent preload distribution across mating surfaces. At 2.160 inches in length, this stud is sized for applications requiring moderate engagement depth without excess material, making it ideal for compact engine bays and closely-spaced bolt patterns. The black oxide finish enhances durability in harsh environments and provides a professional appearance on visible fastening points.

This broached stud is most beneficial for engine builders, performance shops, and motorsport applications where fastener integrity directly impacts reliability and safety. Common uses include cylinder head studs, intake manifold fastening, and transmission bell housing attachments where elevated temperatures and mechanical stress demand premium materials. Installation requires proper torque sequencing and thread preparation to maximize the stud's load-carrying capacity. When paired with matching nuts and washers, this ARP fastener delivers the consistent performance and longevity expected in professional-grade engine assembly and high-performance build specifications.
