Wheel Lock System 1/2in Acorn Black 20pk

The GORILLA Wheel Lock System 1/2in Acorn Black 20-pack is a professional-grade anti-theft solution designed to protect against wheel theft on vehicles where security is non-negotiable. This set delivers 20 matched lug nuts featuring GORILLA's proven acorn design with spline-drive key mechanism, providing reliable protection across a full set of wheels or extended coverage across multiple vehicles. The closed-end construction and heat-treated steel construction ensure durability under the stresses of daily driving and seasonal weather exposure.

Each nut is precision-manufactured with a 1/2-20 thread specification and 60-degree seat angle, ensuring proper fitment on standard vehicle lug holes and secure torque application. The black chrome finish resists corrosion and provides a factory-appearance aesthetic that matches OEM lug nuts. The spline-drive system requires the included key for removal, making casual wheel theft impractical while remaining accessible to the owner. Heat-treatment of the steel core increases hardness and prevents galling or stripping during installation and removal cycles—a critical consideration for vehicles that undergo seasonal wheel changes or track use.

This 20-pack configuration covers a complete four-wheel set with five nuts per wheel, allowing for replacement of worn fasteners or installation across two separate vehicles. Buyers managing fleet vehicles, off-road trucks, or high-value sport vehicles benefit from the redundancy and cost-per-nut efficiency of the pack format. The system is compatible with most standard wheel hub designs that accept 1/2-20 lug nuts and works effectively whether wheels are stored on the vehicle or changed seasonally.
