3/8 Stud - 3.750 Long Broached

The ARP 3/8 Stud - 3.750 Long Broached (MPN: AJ3.750-1LB) is a precision fastening component engineered for high-performance engine assembly and critical load applications. This 3/8-16 and 3/8-24 threaded stud delivers the reliability demanded in racing engines, turbocharged builds, and heavy-duty machinery where fastener integrity directly impacts performance and safety.

Manufactured from chromoly steel and finished with black oxide coating, this 3.75-inch stud combines material strength with corrosion resistance. The broached design ensures consistent thread engagement and uniform clamping load distribution across the fastening interface. At just 0.11 lbs, the compact 0.65 x 0.6 x 4-inch profile fits tight engine compartments and high-density block configurations typical of modern performance engines. The black oxide finish protects against rust while maintaining a professional, OEM-quality appearance.

This stud is designed for builders and technicians assembling cylinder heads, intake manifolds, and other critical engine components where fastener preload and durability matter. ARP studs are the standard in high-revving and forced-induction applications where conventional bolts can fail under thermal cycling and vibration. Sold individually, each stud is ready for torque-to-yield or controlled-preload fastening sequences specified by your engine builder or manufacturer.

ARP fasteners are recognized across automotive performance, marine, and industrial sectors for uncompromising quality and repeatable results. Whether you're building a competition engine, restoring a classic with modern reliability, or maintaining industrial equipment, precision studs like this ARP 3/8 x 3.750 broached stud ensure your assembly meets specification and holds under stress.
