    Reach Deep 10mm Fasteners Without Losing Socket Control

    This Ko-ken extension universal socket combines reach and flexibility in one piece—ideal when a standard socket + extension can’t stay aligned. The 250mm length helps you get past hoses, brackets, and housings, while the universal-style head helps maintain engagement on offset fasteners. 6-point opening for solid contact on 10mm hex heads.

    What It’s For (Real-World Use)

    • Reaching recessed 10mm fasteners where wobble extensions over-angle and pop off
    • Working around obstructions (lines, harnesses, brackets) while keeping the socket seated
    • Service work where you need reach plus a little articulation without swapping setups

    Why 6-Point Matters

    • Better contact area on the fastener flats than 12-point
    • Helps reduce rounding on tight or slightly worn 10mm hex heads

    Compatibility

    • Any 3/8" drive ratchet, breaker bar, torque wrench, or impact-rated 3/8" drive tool
    • Designed for 10mm hex fasteners (metric)

    In the Box

    • 1x 3/8" Drive Extension Universal Socket, 10mm, 250mm length (6-point)

    Safety Notes

    • Always fully seat the socket before applying load
    • Use steady pressure to keep the universal head aligned on the fastener
