7/16 Stud - 5.500 Long Broached w/1.000 Thread

The ARP 7/16 Stud - 5.500 Long Broached with 1.000 Thread (MPN: AP5.500-1LGB) is a precision fastener engineered for high-performance engine assembly and critical structural applications where load-bearing reliability is non-negotiable. This broached stud delivers consistent clamping force and alignment integrity across repeated assembly and disassembly cycles, making it essential for applications requiring fastener permanence and repeatability.

Manufactured from chromoly steel and finished in black oxide, this 5.5-inch stud combines material strength with corrosion resistance suitable for both internal engine environments and exposed mounting conditions. The broached design eliminates rotation during installation, preventing stripped threads and ensuring correct torque values are achieved without slippage. The 1.000-inch threaded section provides ample engagement depth for secure fastening, while the 7/16-inch diameter is compatible with both 7/16-14 and 7/16-20 thread pitches, offering flexibility across different fastening standards and specifications.

This stud is specified for engine block assembly, cylinder head mounting, intake manifold securement, and other load-critical applications where fastener failure is not an option. ARP studs are widely recognized for their precision manufacturing and superior clamp load consistency, particularly in high-horsepower and turbocharged engine builds where expanded metal and thermal cycling demand fasteners that maintain their clamping force over time. The universal design accommodates both stock and custom engine configurations.

Each stud ships individually, allowing builders and machine shops to source exactly the quantity required for their application without excess inventory.
