    Twist-On Extraction for Rounded Bolts & Nuts

    The Ko-ken RS2127/10 Nut Twister set is built for removing rounded-off bolts and nuts using a helical tooth design that bites down and locks as you turn. Use the correct size, seat it fully, and it will grip damaged fasteners for reliable extraction. Includes 10 sockets (4–10mm) organized on a 150mm rail for fast access.

    What It’s For

    • Rounded-off hex bolts and nuts that standard sockets slip on
    • Small fasteners where you still want a 1/4" drive setup
    • Stud bolts and cap bolts (when the fastener isn’t broken and the correct size is used)

    How It Works

    • The six teeth use a helical taper that “cams” inward as you turn, increasing bite on the damaged fastener
    • More turning force = more lock, helping prevent further rounding

    How to Use (Quick Steps)

    1. Pick the correct size (don’t force an undersized socket).
    2. Push the socket fully onto the rounded fastener.
    3. Turn steadily to extract; re-seat if it starts to climb.
    4. Once removed, replace the damaged hardware.

    Pro Tips for Better Grip

    • Clean heavy rust/scale off the fastener first so the teeth can bite.
    • Use straight, controlled torque (avoid wobble that can unseat the socket).
    • If access allows, tap the socket on gently to fully seat it before turning.
