3/8 Stud - 2.500 Broached

The 3/8 Stud - 2.500 Broached is a precision fastener engineered for high-performance applications where reliable clamping and load transfer are critical. Manufactured by ARP, a leader in fastener technology for automotive and industrial use, this chromoly stud is designed for technicians and engine builders who demand consistent performance under extreme conditions. Whether you're assembling high-horsepower engines, critical structural connections, or applications requiring repeatable torque values, this broached stud eliminates the guesswork and delivers dependable results.

This fastener features a 3/8-inch diameter with dual thread pitches (3/8-16 and 3/8-24), extending 2.5 inches in length and manufactured from chromoly steel for superior strength-to-weight ratio and fatigue resistance. The broached design ensures precise thread geometry, allowing for accurate preload distribution and reduced run-out—essential for maintaining bolt clamp load integrity under vibration and thermal cycling. The black oxide finish provides corrosion resistance while maintaining a professional appearance, and the universal design accommodates standard thread configurations across multiple applications without compatibility concerns.

Engine builders, machine shops, and performance technicians rely on ARP studs for applications including cylinder head assemblies, intake manifold fastening, and transmission case securing. The broached construction eliminates chasing and reworking, saving installation time while guaranteeing thread concentricity. Each stud is sold individually, allowing precise inventory control and replacement of worn or damaged fasteners without purchasing full kits. This product is ideal for rebuild projects, competition engines, or any application where fastener reliability directly impacts performance and longevity.
