1/2 Stud - 5.000 Long Broached w/1.250 Thread

The ARP 1/2 Stud - 5.000 Long Broached with 1.250 Thread is a precision fastener designed for specific applications in engine assembly, particularly in high-performance builds and cylinder head installations. This stud is favored by mechanics and engine builders for its reliability and strength in critical structural applications.

Featuring a broached design, the stud provides enhanced load distribution and reduces tensile stress concentration compared to standard bolts. Its 5-inch length is suitable for deep mounting bosses and thick gasket stacks, ensuring proper alignment during installation. The proprietary metallurgy and heat treatment process contribute to consistent preload values, which are essential for maintaining clamping force.

Ideal for those involved in engine rebuilding and custom installations, this stud is compatible with various engine components, ensuring a secure fit. Its precision threading allows for accurate torque-to-yield performance, making it a reliable choice for high-RPM applications.
