Wheel Mate Muteki SR48 Open End Lug Nuts – Yellow Chrome 12×1.50 48mm
The Wheel Mate Muteki SR48 32906Z Open End Lug Nuts are a high-security, performance-driven wheel lug set in vibrant yellow chrome finish for 12×1.50 thread pitch wheels. This set includes 20 pieces (typically 16 standard lugs + 4 locks with key), providing full wheel security and a bold, eye-catching appearance. Machined from high-strength steel with a durable yellow chrome plating, these lugs feature Project Kics’ signature knurled collar for easy hand-tightening and precise torque application. The open-end design allows longer wheel studs to protrude for a custom look, while the 48mm length accommodates thick aftermarket wheels and spacers. Ideal for JDM, tuner, or performance vehicles running 12×1.50 lugs, offering both standout style and theft protection without compromising wheel fitment or balance.
