3/8" Sq. Dr. Locking Wobble-Fix Extension Bar Set – 3 Piece

The Wobble-Fix Extension Bar Set combines precision engineering with enhanced versatility, offering two distinct modes for secure socket control. Designed for demanding workshop conditions, these extension bars ensure both stability and flexibility—whenever you need it.

Each bar features the innovative Wobble-Fix mechanism, allowing you to choose between:

Fix Mode: The socket is held firmly and precisely in line with the drive, eliminating movement for accurate torque transmission. In this mode, the socket cannot be detached from the drive, ensuring maximum security during high-torque applications.
Wobble Mode: The socket can pivot freely up to 15°, providing improved access to fasteners in confined or awkward spaces. Once in Wobble Mode, the locking mechanism prevents the socket from being pushed back into Fix Mode, ensuring consistent operation and preventing accidental mode changes during use.

Manufactured from premium chrome vanadium steel with a mirror-polished chrome finish, these extension bars deliver exceptional strength, durability, and corrosion resistance.

Set Includes:

75 mm Extension Bar
125 mm Extension Bar
250 mm Extension Bar

Dual-function Wobble-Fix design for either rigid or flexible operation
