    Ko-ken 3/8 Sq. Dr. Extension Universal Socket 10mm, 6-Point, 150mm

    A long-reach 3/8" drive 10mm universal extension socket with a 6-point profile—built to access recessed or obstructed fasteners without stacking multiple adapters.

    Overview

    Overview

    The Ko-ken 13146M.150-10 is a 3/8" drive extension universal socket designed for hard-to-reach 10mm fasteners. The built-in universal section helps you work at slight angles where a straight extension and socket won’t line up, while the 6-point socket profile provides solid engagement on hex fasteners.

    Best Use Cases

    Best Use Cases

    • Reaching 10mm fasteners behind brackets, shields, and accessory mounts
    • Working around coolant lines, harnesses, and hard lines where a straight shot isn’t possible
    • Accessing recessed 10mm bolts/nuts without adding multiple extensions + wobble + socket
    How to Use

    How to Use

    1. Attach the socket to any 3/8" drive ratchet/torque wrench.
    2. Keep the working angle small and controlled (universal sockets work best at slight angles).
    3. Seat the 6-point end fully on the fastener before applying torque.

    FAQ

    Q: Is this the same as a wobble extension?

    A: Similar purpose (helping when you’re not perfectly straight), but this is a single-piece extension universal socket—socket + universal reach combined.

    Why 6-point instead of 12-point?

    A: 6-point typically provides stronger contact on hex fasteners and can reduce the chance of rounding compared to 12-point in high-resistance situations.

    What category should this live in?

    A: Extension Bars is the primary fit (it’s fundamentally a reach tool). Universal Joints is a logical secondary collection because the universal section is the key feature.
