Triple Square Drive

About Triple Square Drive

Triple square drive wrenches, also called XZN keys, are a specialty hand tool built around a 12-point star profile that standard hex or Torx tools cannot engage. They appear almost exclusively on European vehicles, particularly German makes, where triple square fasteners secure wheel bolts, CV axle bolts, transmission drain plugs, and select engine components. If you own or work on Audi, Volkswagen, BMW, or similar vehicles, a triple square set is not optional equipment. The products curated here range from single-piece keys to complete 10-piece sets spanning the common XZN fastener sizes. The LEXIVON LX-145 leads the field with 14,700 reviews and 1,000 units bought last month, pointing to outsized real-world demand compared to the rest of the category. Sets of 8 to 10 pieces cover the most common fastener sizes in one purchase: the NEIKO 10078A offers 10 pieces at 120 millimeters for $13.70, while the CARBYNE 3101563 goes premium with 8 pieces at $94.98 for buyers who need professional-grade hardware in a shop setting. Prices in this category run from $5.50 for a single Capri CP30356 key up to $94.98 for the CARBYNE 3101563 set. Buyers who need only one specific size save money with a single key; those who tackle multiple jobs or different vehicle models benefit from a complete set. Rating floors are high across the board, with seven of the ten products carrying a 4.7-star or better rating, so the deciding factors come down to piece count, key length, and how frequently the tool will be used.
