7/16 Stud - 4.500 Long Broached w/1.000 Thread

The 7/16 Stud - 4.500 Long Broached w/1.000 Thread is an ARP precision fastener engineered for high-performance engine builders, machine shops, and enthusiasts who demand reliable clamping in critical applications. This broached stud serves as a replacement or upgrade component in engine assembly, cylinder head fastening, and other load-bearing connections where consistent preload and repeatability are essential. ARP studs are industry-standard for professional rebuilds and competition engines due to their superior metallurgy and manufacturing tolerances.

Manufactured from chromoly steel and finished in black oxide for corrosion resistance, the 7/16 Stud - 4.500 Long Broached w/1.000 Thread features broached construction that ensures accurate thread geometry and minimizes runout. The dual-thread configuration—supporting both 7/16-14 and 7/16-20 thread pitches—provides flexibility for different assembly requirements and engine platforms. Black oxide coating protects against rust while maintaining consistent friction characteristics during installation, which is critical for accurate torque-angle preload calculations in precision engine work.

This fastener is ideal for engine builders upgrading factory hardware, machine shops performing cylinder head work, and racers preparing engines for competition where fastener failure is not an option. The 4.5-inch length and 7/16-inch diameter accommodate standard engine block and head configurations across many platforms. Installation requires proper torque specs and use of ARP lubricant to ensure design preload is achieved; always consult engine-specific specifications and ARP documentation for correct fastening procedures.
