Abstract
A screwdriver system can include a primary driver and a secondary driver. The primary driver can include an attachment feature configured to couple to a driver bit socket. The attachment feature can be mechanically coupled to the driver shaft such that torque applied to the attachment feature is transferred to the shaft. The secondary driver can include a driver bit socket at the end of its shaft. The attachment feature of the primary driver can be structured, configured, and oriented such that the secondary driver can reversibly couple to the attachment feature via the driver bit socket of the secondary driver shaft. The secondary driver, when so-coupled, can be oriented with the primary axis of the secondary driver shaft generally perpendicular to the primary axis of the primary driver. In some examples, the primary driver can be a torque wrench.
