The 12mm x 1.75 Stud 4.750 Long Broached from ARP is a premium fastening solution designed for high-performance engine builds and critical structural applications. These studs are essential for mechanics and engine builders working on turbocharged, supercharged, or heavily modified powerplants where standard bolts cannot withstand extreme clamping loads and thermal cycling. Whether you're assembling cylinder heads, intake manifolds, or exhaust housings on a performance engine, ARP studs deliver the reliability and consistency that separates a dependable build from a catastrophic failure.
ARP studs utilize a broached design that ensures precise thread geometry and superior clamping force consistency across the entire fastener. The 12mm diameter with a 1.75 pitch thread combines robust load-carrying capacity with fine thread engagement, maximizing holding power in aluminum and cast-iron applications. At 4.750 inches long, this stud accommodates deeper counterbores and thicker component stacks common in modern engine architectures, while the broached design delivers predictable preload values and reduced joint relaxation over time.
Professional builders, engine machine shops, and serious automotive enthusiasts trust ARP fasteners for applications ranging from daily-driven modified engines to all-out competition builds. These studs are compatible with standard ARP washers and nuts, making installation straightforward and efficient. With their superior engineering, ARP studs are a reliable choice for anyone looking to enhance the performance and durability of their engine builds.
