MPN: AP5.000-1LB
The ARP 7/16 Stud - 5.000 Long Broached with 1.000 Thread (MPN: AP5.000-1LB) is a precision-engineered fastener designed for high-strength mechanical assemblies requiring dual-thread capability. This broached stud accommodates both 7/16-14 and 7/16-20 thread pitches, making it ideal for applications where compatibility across multiple fastener standards is essential. Manufactured from chromoly steel with black oxide finish, this fastener delivers corrosion resistance and strength suitable for automotive, motorsports, and industrial clamping operations.
The 5-inch overall length and 1-inch threaded section provide substantial grip length for secure engagement in deep or thick assemblies. Broaching — a precision machining process — ensures consistent thread geometry and eliminates galling, allowing studs to be installed and removed repeatedly without degradation. The chromoly material specification offers tensile strength superior to standard steel, critical for high-load or vibration-prone installations common in engine block repair, transmission work, and structural reinforcement. Black oxide coating provides mild corrosion protection suitable for shop and field environments, though not recommended for prolonged exposure to saltwater or caustic chemicals.
This universal stud is specified by professionals in engine rebuilding, frame repair, and heavy equipment maintenance where dual-pitch threading flexibility is required. Its 7/16-inch diameter accommodates standard wrench sizes (5/8-inch) and matches common bolt patterns in older and newer vehicle platforms. Each unit ships individually, allowing technicians to source exact quantities needed for targeted repairs without excess inventory.
ARP studs are widely recognized in motorsports and professional service environments for dimensional consistency and material quality control. The combination of broached precision, dual-thread accommodation, and chromoly strength makes this fastener a dependable choice for applications where standard single-pitch studs lack versatility or where bolt replacement and reusability are production requirements.
