    Reach Deep Fasteners Without Losing Socket Grip

    This Ko-ken 3/8" drive extension universal socket combines a 14mm 6-point socket with a long 250mm reach and a universal joint. It’s built for bolts and nuts you can’t hit straight-on—behind brackets, around housings, or down in engine bays—while keeping solid 6-point contact to help reduce rounding.

    Why This Tool Exists

    • Universal joint built in: helps you access fasteners at an angle when a straight extension won’t line up
    • Long reach: 250mm length gets past obstructions and into recessed locations
    • 6-point socket: better bite on stubborn fasteners vs 12-point in many real-world cases

    Common Use Cases (Shop-Friendly)

    • Reaching mounting bolts behind pumps, brackets, and guards
    • Hardware near frames/rails where your ratchet can’t stay straight
    • Deep or recessed 14mm fasteners where a normal socket + wobble stack is too bulky

    How to Use (Quick Steps)

    1. Seat the 14mm socket fully on the fastener (make sure it’s bottomed out).
    2. Keep the joint angle as shallow as possible for maximum strength and control.
    3. Break loose smoothly—avoid side-loading the head at extreme angles.

    Notes

    • Best practice: use the least angle needed—extreme angles reduce effective torque transfer.
    • Always confirm 14mm is the correct size before applying force to avoid slipping/rounding.
