Stud 11mm x 2.0 5.150in OAL

The Stud 11mm x 2.0 5.150in OAL is a precision fastener engineered for high-performance tactical and automotive applications where vibration resistance and secure clamping are mission-critical. ARP studs are purpose-built for operators and technicians who demand repeatability and reliability under extreme conditions—whether securing critical components in AR platform assembly, engine block work, or other load-bearing applications. This stud's 5.150-inch overall length makes it ideal for through-bolt configurations requiring controlled thread engagement and proper clamp load distribution.

ARP studs are manufactured to exacting tolerances and feature shot-peened surfaces that increase fatigue strength and resist stress-concentration failures common in standard fasteners. The 11mm diameter with 2.0mm pitch threading delivers optimal load distribution for precision-critical assemblies, while the precisely controlled 5.150-inch length ensures correct engagement depth without over-torquing or thread stripping. Lightweight at only 0.18 lbs, this stud maintains minimal mass penalty while delivering the clamping force required in high-vibration environments typical of tactical and motorsport applications.

Operators, gunsmiths, and powersports technicians rely on ARP fasteners for engine builds, upper receiver assembly, and critical structural connections where standard hardware may fail under recoil, thermal cycling, or sustained vibration. Proper installation requires torque wrench application and adherence to manufacturer specifications; over-torquing voids the integrity benefits of precision engineering. This stud is compatible with metric 11mm threaded holes and pairs with ARP nuts (sold separately) to create a matched fastening system that resists loosening and maintains clamp load integrity through thousands of operational cycles.
