Triple Square Drive

Triple Square Drive, also known as XZN, is a type of screw drive with a three-pointed, star-shaped socket. It is commonly used in automotive applications, particularly in German-made vehicles. The name "Triple Square" is derived from the fact that it has three short 90-degree angles within the recess.

Here are some key points about Triple Square Drive:

  1. Applications: Triple Square Drive sockets are often used in applications where high torque is required, making them suitable for automotive components such as cylinder head bolts, axle bolts, and other critical fasteners.

  2. Tool Design: The Triple Square Drive tool typically consists of a socket with a corresponding triple square bit or driver. The bits or drivers are available in various sizes to accommodate different fastener dimensions.

  3. Common Sizes: Common sizes for Triple Square Drive fasteners include 4mm, 6mm, 8mm, 10mm, and 12mm.These sizes are often used in various automotive systems.

  4. Vehicle Brands: While Triple Square Drive is used in different applications, it is notably associated with German car manufacturers such as Volkswagen, Audi, BMW, and Mercedes-Benz. These manufacturers often use this type of fastener in critical engine and transmission components.

  5. High Torque Applications: One of the main advantages of Triple Square Drive is its ability to handle high torque without slipping. This makes it particularly useful in situations where a secure and tight fit is crucial.

  6. Socket Sets: Triple Square Drive sockets are commonly included in socket sets designed for automotive repair and maintenance. These sets may contain a variety of socket sizes and accessories to accommodate different fasteners.

  7. Material and Durability: Triple Square Drive sockets and bits are typically made from durable materials such as chrome vanadium steel to withstand the high torque loads encountered in automotive applications.

  8. Usage Tips: When using Triple Square Drive tools, it's important to ensure a good fit between the tool and the fastener to prevent rounding or damaging the fastener head. Additionally, following the manufacturer's torque specifications is crucial to avoid over-tightening.

Overall, Triple Square Drive is a specialized screw drive that plays a significant role in the automotive industry, especially in German-made vehicles. It offers a reliable solution for applications requiring high torque and a secure fit.
