Features and Benefits:

• The 3/8" Square Drive Locking Wobble-Fix Extension Bar Set is built to deliver maximum control, safety, and versatility in demanding workshop environments. This three-piece set features an advanced dual-function Wobble-Fix design that allows seamless switching between rigid Fix Mode for precise, in-line torque transfer and flexible Wobble Mode, which provides up to 15° of controlled pivot for accessing fasteners in tight or obstructed spaces. In Fix Mode, the socket is securely locked to prevent detachment during high-torque applications, while in Wobble Mode, an integrated locking mechanism ensures the setting remains unchanged during use. Manufactured from premium chrome vanadium steel with a durable mirror-polished chrome finish, these extension bars offer exceptional strength, corrosion resistance, and long-term reliability. The set includes 75 mm, 125 mm, and 250 mm extension bars, making it an ideal solution for automotive, industrial, and general maintenance professionals who require both precision and reach.
