5/16-18 Stud 2.850 OAL w/Top Guide Nose

The ARP 5/16-18 Stud 2.850 OAL w/Top Guide Nose is a precision fastening component engineered for high-performance engine assembly and critical load-bearing applications. Designed for builders and technicians who demand reliability under extreme conditions, this stud serves as a foundation for secure, repeatable clamping in demanding environments. Whether you're assembling a race engine, rebuilding cylinder heads, or managing industrial fastening projects, this chromoly stud delivers the consistency and strength required for applications where failure is not an option.

Manufactured from chromoly steel and finished with black oxide coating, the 5/16-18 Stud 2.850 OAL w/Top Guide Nose combines material durability with corrosion resistance. The 2.850-inch overall length and integrated top guide nose design ensure proper alignment and consistent clamping geometry during installation, reducing the risk of cross-threading or misalignment. The dual-thread configuration (compatible with both 5/16-24 and 5/16-18 standards) provides versatility across different engine platforms and fastening systems, while the black oxide finish protects against oxidation and wear during storage and use.

This stud is ideal for engine builders, automotive technicians, and performance shops working on small-block and big-block applications where ARP fastening systems are specified. The guide nose feature prevents damage to the tapped hole and ensures repeatable torque values, critical for maintaining proper head gasket compression and clamping load. Installation is straightforward with standard sockets and wrenches; apply appropriate anti-seize compound and torque to manufacturer specifications for your engine platform. Sold individually, allowing you to replace damaged studs or build complete fastening kits tailored to your engine assembly needs.
