16 Lugnuts 9/16 Duplex Acorn

The GORILLA 16 Lugnuts 9/16 Duplex Acorn (SKU GOR76198) is a complete wheel fastener set engineered for serious automotive builders, restorers, and everyday drivers who demand reliability under stress. Whether you're assembling a custom build, replacing worn fasteners after years of service, or upgrading to premium hardware, this 16-pack delivers the security and durability your wheels need. Duplex acorn lug nuts are the industry standard for performance and street applications—they combine robust holding power with a clean, finished appearance that complements any wheel style.

These 9/16-18 right-hand thread fasteners feature a 7/8-inch hex head and a 60-degree seat design that ensures precise, repeatable torque application and eliminates slippage during installation and removal. The closed-end acorn design protects the thread from corrosion, road salt, and debris—critical for longevity in harsh driving conditions. Chrome-plated steel construction provides superior corrosion resistance while maintaining the structural integrity required to withstand vibration, temperature cycling, and the dynamic forces generated by acceleration, braking, and cornering. The full set of 16 nuts (4 per wheel, plus spares) weighs 3.39 lbs and arrives ready to install.

Mechanics and enthusiasts building muscle cars, trucks, drift platforms, and daily drivers consistently specify GORILLA lug nuts for their reliability and precise manufacturing tolerances. The 9/16-18 thread pitch and 60-degree seat are compatible with most domestic and import vehicles manufactured from the 1970s forward—verify your vehicle's specific lug pattern before purchase. Always torque to manufacturer specification (typically 80–120 ft-lbs for most applications) using a calibrated wrench or impact gun, and re-torque after the first 50–100 miles of driving to account for initial settlement and seal-down of the seat.
