3/8 Stud - 3.250 Broached

The ARP 3/8 Stud - 3.250 Broached (Part No. AJ3.250-1B) is a precision fastening component engineered for high-performance applications requiring critical thread consistency. This broached stud features 3/8-16 and 3/8-24 threading options, a 3.25-inch length, and black oxide finish on chromoly construction. Broached studs maintain exact dimensional tolerances and uniform thread profile, making them essential for engine assembly, performance automotive builds, and structural applications where fastener reliability directly impacts system integrity.

The 3.250-inch length provides sufficient engagement depth for load-critical joints while remaining compact enough for confined assembly spaces. Chromoly material offers superior tensile strength and fatigue resistance compared to standard steel, while black oxide coating provides corrosion protection and reduces galling during installation. The broached design ensures each stud delivers identical thread geometry—critical for applications where fastener consistency prevents joint relaxation, vibration loosening, or uneven load distribution.

Buyers select ARP studs for engine rebuilds, head gasket sealing, transmission mounting, and structural repairs where factory fasteners prove inadequate. The dual-pitch option (3/8-16 and 3/8-24) accommodates diverse OEM and custom specifications. Individual stud purchase allows targeted replacement of damaged fasteners without buying complete kits, reducing waste and cost on precision repair jobs where only one or two studs need replacement.

ARP is recognized in performance and motorsport circles for fastener engineering that meets or exceeds OEM and competition-grade standards. The 3/8 Stud - 3.250 Broached represents the precision fastening category where tolerances matter—specifications that separate reliable assemblies from field failures.
