1/2-20 Lug Nuts (5pk)

The 1/2-20 Lug Nuts (5pk) from MOROSO are precision-engineered fasteners designed for mechanics and automotive enthusiasts who demand secure, reliable wheel attachment across high-performance and stock applications. These lug nuts serve as the critical link between your wheel and hub assembly, and choosing the correct specification is fundamental to vehicle safety and appearance. Whether you're building a custom hot rod, restoring a classic, or maintaining daily drivers, having the right lug nut specification ensures proper clamping force and eliminates the risk of wheel loosening under acceleration, braking, or cornering stress.

Built from hardened steel with a black oxide finish, the 1/2-20 Lug Nuts feature a 3/4-inch hex head and 60-degree seat design that matches OEM specifications on thousands of vehicles. The right-hand thread and open-end design allow for quick installation and removal using standard lug nut sockets, while the 60-degree conical seat provides optimal contact geometry with matching wheel lug holes. Black oxide coating resists corrosion and maintains a professional appearance while protecting against rust, especially important in salt-exposed climates or high-moisture environments. The 1/2-20 thread pitch denotes a half-inch diameter shaft with 20 threads per inch—a common metric across domestic and import platforms.

Technicians and DIY builders rely on MOROSO's 1/2-20 Lug Nuts for wheel reinstallation after brake service, tire rotations, suspension work, or complete wheel upgrades. The five-pack quantity covers most single-wheel repairs or serves as a backup set for your tool kit. Verify your vehicle's original lug nut specification—printed on the wheel or in the owner's manual—before purchase, as thread pitch and seat angle must match exactly to ensure proper seating and torque retention. Always torque lug nuts to manufacturer specifications (typically 80–130 ft-lbs for 1/2-20 fasteners) using a calibrated wrench to achieve safe, repeatable clamping force.
