7/16 Stud - 3.750 Short Broached

The ARP 7/16 Stud - 3.750 Short Broached (Part Number AP3.750-1SB) is a precision-engineered chromoly fastener designed for critical high-performance engine and drivetrain applications. Built from chromoly steel and finished in black oxide, this broached stud delivers the strength and corrosion resistance required in demanding mechanical assemblies where standard fasteners fall short.

Measuring 3.75 inches in length with a 7/16-inch diameter, this stud accommodates both 7/16-14 and 7/16-20 thread pitches, offering flexibility across different bolt pattern configurations. The broached design ensures consistent, precise thread engagement without galling or stripping—critical for applications subject to thermal cycling and high stress. Chromoly's superior strength-to-weight ratio and fatigue resistance make it the material of choice for connecting rods, head studs, and transfer case assemblies where reliability under load is non-negotiable. The black oxide coating provides baseline corrosion protection suitable for engine compartment environments.

This fastener is engineered for serious builders and technicians working on performance engines, race applications, and heavy-duty off-road vehicles. Whether you're assembling a competition motor, reinforcing a transfer case, or rebuilding a high-mileage drivetrain, ARP studs are recognized for their engineering integrity and consistent performance. The individual stud format allows you to replace or upgrade fasteners as needed without purchasing a complete kit.

ARP has established its reputation in motorsports and heavy-duty applications by focusing on fastener metallurgy and precision manufacturing. A 7/16 stud in this size range is commonly used in engine block applications, transmission housings, and accessory mounting where a broached thread profile delivers superior clamp load retention compared to rolled-thread alternatives. Weight is minimal at 0.15 lbs per stud.
