4 Lug Nuts 12mmx1.5 Acorn Bulge Seat

The 4 Lug Nuts 12mmx1.5 Acorn Bulge Seat from GORILLA (SKU GOR41137) are precision-engineered fasteners designed for vehicles requiring metric lug nut specifications. These closed-end acorn-style lug nuts secure your wheels with the dependability that serious automotive enthusiasts and mechanics demand, whether you're building a performance machine or maintaining daily transportation. The set of four provides a complete solution for wheel installation on vehicles equipped with 12mm x 1.50 right-hand threaded wheel studs, making them essential components for proper wheel retention and safety.

Constructed from durable steel with a chrome finish, these lug nuts feature a 60-degree acorn bulge seat design that ensures positive engagement with matching wheel hub surfaces. The 3/4-inch hex head provides optimal leverage and grip during installation and removal, reducing the risk of rounding or stripping when using impact wrenches or torque wrenches. The closed-end design protects the stud threads from dirt, moisture, and corrosion—critical for longevity, especially in harsh climates or off-road environments. Chrome plating offers both aesthetic appeal and corrosion resistance, maintaining a professional appearance while defending against rust and oxidation over extended service intervals.

Mechanics and vehicle modifiers benefit most from this set when upgrading wheels, performing suspension work, or replacing worn fasteners on metric-threaded platforms common in European and Asian vehicles. Proper installation requires matching torque specifications to your vehicle's manual—typically 80–100 ft-lbs for most applications—using a calibrated torque wrench to prevent under- or over-tightening. Verify that your wheel hub studs are indeed 12mm x 1.50 right-hand thread before purchase; mismatched lug nuts compromise wheel security and create safety hazards. This four-pack is ideal for one-wheel replacement or as a maintenance set for complete wheel service on smaller platforms.
