The TOTAL Tools THMLNS031 3Pcs Non-Marring Lug Nut Socket Set is a professional wheel service tool kit designed for safe installation and removal of lug nuts without damaging alloy wheels. Ideal for automotive workshops, tire service centers, and professional mechanics, this set provides reliable performance while protecting premium wheel finishes.

Manufactured from high-strength CrMo (Chrome Molybdenum) steel, the sockets are engineered to withstand high torque and impact applications. The heat-treated construction enhances durability, wear resistance, and long service life, making them suitable for repeated use with impact wrenches.

Each socket is equipped with a protective nylon sheath that helps prevent scratches, scuffs, and damage to alloy wheel surfaces during operation. This non-marring design makes the set ideal for luxury vehicles, sports cars, and premium alloy wheel applications.

The set includes the three most commonly used lug nut sizes—17mm, 19mm, and 21mm—providing excellent versatility for a wide range of vehicles. The color mirror processing allows quick identification of socket sizes while adding corrosion resistance and a professional appearance.

Supplied in a durable BMC storage case, the sockets remain organized, protected, and easy to transport between job sites.
