    Ko-ken 3/8" Sq. Dr. Extension Universal Socket 8mm (6-Point) – 250mm
    Overview

    Overview

    This Ko-ken 3/8" drive extension universal socket combines a 6-point 8mm socket with a built-in universal joint and a long 250mm reach. It’s built for fasteners that are recessed, partially blocked, or slightly misaligned—where a straight socket can’t stay engaged.

    Key Benefits

    • Long 250mm reach to access deep or obstructed fasteners
    • Universal joint head helps maintain engagement at slight angles
    • 6-point profile for a more secure bite on fasteners
    • One-piece solution: fewer adapters, less slop than stacking extensions + wobble + u-joint

    Common Use Cases

    • Reaching 8mm fasteners behind brackets, lines, hoses, or harnesses
    • Tight access spots where the ratchet can’t stay perfectly in-line
    • Light angle corrections without switching to separate universal joints
    • Deep-set fasteners in engine bays, equipment panels, and service access points

    Why 6-Point Matters

    • Better contact on the flats of the fastener compared to 12-point
    • Helps reduce rounding on tighter or more stubborn fasteners
    • Ideal when you need maximum grip in a compact head

    How To Use

    • Keep the socket as straight as possible for best grip, and only use the swivel angle you need
    • Apply steady force—avoid sudden side-loading at extreme angles
    • If a fastener is seized, consider penetrating oil and controlled breakaway instead of forcing high-angle torque
