    Ko-ken 3/8 Sq. Dr. Locking Wobble-Fix Extension Bar 3 Piece Set
    Lock the Socket On, Then Add Wobble When You Need It

    Lock the Socket On, Then Add Wobble When You Need It

    This Ko-ken Wobble-Fix extension set gives you two working modes in the same bar: a rigid “Fix Mode” for straight, secure torque transfer and a “Wobble Mode” that lets the socket pivot up to 15° for tight access. The locking mechanism keeps the socket secure and prevents accidental mode changes while you’re working. Built from chrome vanadium steel with a mirror-polished chrome finish for durability and corrosion resistance.

    Why Wobble-Fix Is Different

    • Fix Mode: keeps the socket perfectly in line for accurate torque transmission and a locked-on connection.
    • Wobble Mode: gives up to 15° of angle to reach fasteners around obstructions—while staying locked and preventing accidental push-back into Fix Mode.

    In the Box

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

    How to Use (Quick Steps)

    1. Attach your socket to the extension.
    2. Choose Fix Mode for straight, controlled torque.
    3. Switch to Wobble Mode when you need angle access (up to 15°) in tight spaces.

    Best Use Cases

    • Reaching recessed fasteners without losing socket control
    • Working around hoses, wiring looms, frames, and brackets
    • Tight-access hardware where a standard straight extension won’t line up cleanly

    Safety Notes

    • Keep the drive fully seated before applying force.
    • Use Fix Mode when maximum straight-line torque control is required.
    • Avoid side-loading beyond the intended working angle
