A torque wrench head, also known as an interchangeable head for a torque wrench, is a specialized tool attachment designed to be used with Interchangeable Head Torque Wrenches. These heads come in various types and sizes to accommodate different fasteners and applications. They enhance the versatility of torque wrenches by allowing users to switch out the head to match the specific requirements of the task at hand. This capability is particularly useful in professional settings such as automotive repair, aerospace, and industrial maintenance where precision and adaptability are crucial.
History
[edit]The first interchangeable head torque wrench was designed by Acutum in 2009.
Types
[edit]Torque wrench heads come in several types, each designed for specific applications and fastener types. Common interface sizes include 9×12mm and 12×14mm, and interchangeable heads include open-end, ring-end, adjustable, ratchet, etc.:[1][2]
Open-End Head

An open-end head has a U-shaped opening that allows it to grip two sides of a fastener. Ideal for situations where access to the fastener is limited or where a closed socket cannot be used.
Ring(Box)-End Head

This type encircles the fastener completely, providing a more secure grip. Used when a strong, reliable connection is needed to apply high torque without slipping.
Socket Head
[edit]Designed to accommodate various socket sizes, socket heads are versatile and can be used with different socket types. Commonly used in automotive repair and maintenance to handle different bolt and nut sizes.
Flare Nut Head
[edit]Similar to the open-end head but with a slight curve to better grip flare nuts. Frequently used in plumbing and HVAC applications.
Ratchet Head
[edit]Equipped with a ratcheting mechanism, this head allows for continuous motion without needing to remove and reposition the tool. Speeds up repetitive tasks and is useful in tight spaces.
