4 Lugnuts Acorn Bulge 12mm x 1.5

The GORILLA 4 Lugnuts Acorn Bulge 12mm x 1.5 (SKU: GOR91137HTB) is a professional-grade lug nut set engineered for secure wheel attachment on vehicles requiring metric fastening. These right-hand threaded acorn lugnuts feature a 60-degree seat angle and closed-end design, delivering the precise fitment and corrosion resistance demanded in automotive applications where wheel security is non-negotiable.

Each lugnut in this four-piece set measures 12mm x 1.5 pitch and incorporates a 13/16-inch hex head for reliable torque wrench engagement. The acorn bulge design protects wheel studs while providing a finished appearance. Heat-treated steel construction ensures durability under repeated mounting and removal cycles, while the chrome finish resists rust and corrosion in salt air and wet conditions—critical for extended wheel life. The closed-end configuration prevents debris accumulation and water intrusion, reducing corrosion risk over time.

These lugnuts are designed for vehicle owners and technicians who prioritize proper fastening standards. Metric 12mm x 1.5 lugnuts fit a wide range of import and some domestic vehicles requiring this thread specification. The 60-degree seat matches standard wheel hub geometry, ensuring even pressure distribution and preventing vibration-induced loosening. Technicians and enthusiasts performing wheel replacement, tire service, or vehicle maintenance rely on quality lugnuts to maintain safety and wheel integrity throughout vehicle ownership.
