4 Lugnuts Acorn Bulge Open End 12mm x 1.5

The GORILLA 4 Lugnuts Acorn Bulge Open End 12mm x 1.5 (SKU GOR40037B) is a factory-grade wheel fastening solution designed for vehicles requiring metric thread specifications. This set of four steel lugnuts delivers the reliable clamping force and durability demanded in automotive maintenance, restoration, and field applications where precise wheel retention is non-negotiable.

Each lug nut features a 3/4-inch hex head geometry that accommodates standard socket and wrench sizes, while the 60-degree tapered seat ensures proper engagement with matching wheel lugs and studs. The acorn bulge design protects threads from dirt and corrosion during storage and transport, extending the service life of wheel studs in demanding environments. Zinc plating provides corrosion resistance suitable for both on-road and off-road exposure. The 12mm x 1.5 thread specification matches European and Asian vehicle platforms, including many late-model imports and performance vehicles where metric fasteners are OEM standard.

This four-piece set is ideal for wheel replacement, brake service, suspension work, and tire rotation tasks where OEM-equivalent lugnuts are required. Technicians performing vehicle maintenance, restoration shops rebuilding classic imports, and field teams managing fleet vehicles benefit from having matched metric lug nuts on hand. The open-end design allows for easy installation and removal without interference from wheel components, making these lugnuts practical for situations where sealed or closed designs would complicate assembly.

GORILLA fasteners are recognized for consistent quality and dimensional accuracy across their fastener line, making these lugnuts a dependable choice for applications where proper thread engagement and clamp load are critical to wheel safety and longevity.
