S/S Hex Nyloc Nuts 7/16-14 (5)

The S/S Hex Nyloc Nuts 7/16-14 (5) from ARP are precision-engineered stainless steel fasteners designed for critical applications where vibration resistance and long-term reliability are non-negotiable. These locking nuts are ideal for high-performance automotive, machinery, and industrial assemblies where standard fasteners risk coming loose under operational stress. The set of five provides convenient, ready-to-use hardware for engine builds, transmission work, or any application requiring secure, permanent fastening without secondary locking devices.

Each nut features a nylon insert (nyloc) that grips the bolt threads during installation, creating an effective vibration lock that remains secure across thermal cycling and mechanical shock. The 7/16-14 thread specification matches standard 7/16-inch bolts with 14 threads per inch, commonly used in engine components and drivetrain applications. Manufactured from polished stainless steel, these hex nyloc nuts resist corrosion, maintain appearance in exposed environments, and deliver the durability ARP is known for in performance fastening solutions.

Buyers working on small-block and big-block engines, transmission pans, water pumps, and accessory mounting will benefit from the peace of mind these locking nuts provide. The stainless construction makes them suitable for both street and race applications, particularly where moisture exposure or salt environments demand corrosion resistance. Installation is straightforward—simply thread onto a 7/16-14 bolt and torque to specification; the nylon insert engages automatically, requiring no special tools or assembly procedures.
