Gorilla K5CS-12150BGR Black 12mm × 1.50 Spline Lug Kit

Gorilla K5CS-12150BGR includes 20 black closed-end spline lug nuts with a matching socket for four compatible five-lug wheels. Verify 12mm × 1.50 studs, conical seating, stud engagement and wheel recess clearance before installing.

Product Description

The Acorn closed-end kit groups matching wheel fasteners and a spline installation tool. Its 1.36-inch overall length and closed end make stud protrusion and internal clearance important selection checks.

The manufacturer’s catalog maps this kit to black 21138BC lug nuts and the 1921SD-KEY socket. This is a lug installation kit, not a separate set of unique-pattern wheel locks; use the correct seat geometry and torque instructions for each wheel.

Features & Benefits

  • 20 black steel Acorn closed-end spline nuts.
  • 12mm × 1.50 thread.
  • 60-degree conical seat configuration.
  • 1.36-inch overall length.
  • Matching spline installation socket.

Compatibility & Applications

  • For matching M12 × 1.50 studs and wheels requiring the stated conical seat.
  • Not suitable simply because the wheel has five lugs; seat and thread must match.
  • Verify stud clearance so the closed nut does not bottom out.
  • Follow vehicle and wheel fastening instructions.
