    Reach Hidden 10mm Fasteners Without Separate U-Joints

    This Ko-ken 3/8" drive extension universal socket combines an extension and a universal-style head in one tool, letting you access recessed or obstructed 10mm fasteners with a little angle where a straight socket/extension won’t line up. The 6-point opening helps keep solid contact on the fastener, while the 200mm length adds reach for tight or deep access points.

    Why Use an Extension Universal Socket?

    • Fewer parts to manage: extension + universal in one piece
    • Better access: reach around brackets, lines, and housings
    • Cleaner alignment: helps when you can’t get perfectly straight on the fastener
    • 6-point grip: designed to maintain strong contact vs. multi-point in high-load situations

    Common Use Cases (Shop + Field)

    • Reaching 10mm bolts behind covers, guards, or panels
    • Accessing fasteners near hoses, wiring looms, and hard lines
    • Working on recessed hardware where a standard socket/extension stack is too bulky
    • Tight swing-room areas where small angle changes make the difference
