5/16-18 Stud 2.225 OAL w/Top Guide Nose

The 5/16-18 Stud 2.225 OAL w/Top Guide Nose from ARP is a precision fastening component engineered for high-performance engine and mechanical assemblies where critical clamping force and reliability are non-negotiable. This chromoly stud serves applications requiring superior tensile strength and repeatability, particularly in custom engine builds, race motors, and heavy-duty industrial equipment. Designed as a universal solution, it accommodates both 5/16-24 and 5/16-18 thread pitches, offering flexibility across multiple engine families and specifications.

Manufactured from chromoly steel and finished in black oxide, the 5/16-18 Stud 2.225 OAL w/Top Guide Nose delivers exceptional durability and corrosion resistance while maintaining precise dimensional tolerances critical to proper fastening. The 2.225-inch overall length (OAL) positions this stud for applications requiring controlled clamp loads without excessive thread engagement. The integrated top guide nose facilitates easier installation and alignment during assembly, reducing the risk of thread cross-threading and ensuring consistent bolt preload every time. Black oxide coating provides both cosmetic uniformity and oxidative protection in demanding under-hood or industrial environments.

Performance-focused builders, engine reconditioning shops, and fastener-critical applications benefit most from ARP's engineering precision. Whether upgrading cylinder head assemblies, intake manifolds, or transmission components, the dual thread pitch compatibility and chromoly composition ensure reliable, repeatable clamping without fatigue failure. Installation is straightforward—thread into prepared holes and torque to specification using standard fastener practices. Order the 5/16-18 Stud 2.225 OAL w/Top Guide Nose individually or as part of a complete ARP fastener system for maximum performance and durability.
