Gorilla Automotive 41128BC Black Bulge Acorn Lug Nut, 3/4-Inch Hex, M12-1.25 Thread

The Gorilla Automotive 41128BC Bulge Acorn Lug Nut is a durable wheel-fastening solution designed for applications using an M12-1.25 thread pitch and a 3/4-inch hex. Its black finish provides a clean, understated appearance that complements many aftermarket and factory-style wheels, while the bulge acorn design offers an expanded seating area for added wheel-contact coverage.

Manufactured for dependable service, this lug nut is suited to compatible automotive and light-truck wheel installations. The conical acorn seat helps center the fastener against properly matched tapered wheel seats, and the bulge profile can provide broader coverage than a standard acorn lug nut. Always confirm thread, seat style, hex size, and required engagement before installation, and tighten to the wheel manufacturer’s recommended torque specification.
