    Hold Nuts & Bolts Without Magnets (Deep Sockets)

    Ko-ken’s NUT GRIP® system holds nuts and bolts in the socket without using magnets. Inside the socket, a coil spring and ball bearings apply pressure on opposing flats to retain the fastener, making starts easier in awkward positions. This set gives you five deep 3/8" drive metric sockets (8–14mm) on a compact 150mm rail—ideal for tight access where you still need reach and secure fastener control.

    Why NUT GRIP® (Quick Explainer)

    • Holds nuts/bolts in place without magnets (useful for non-magnetic fasteners)

    • Ball bearings press against opposing flats to keep the fastener seated
    • Helps start threads one-handed and reduces dropped hardware in tight areas

    Best Uses (Real-World Fit)

    • Starting nuts on studs when you can’t support the hardware with your fingers
    • Overhead or vertical fasteners where dropped nuts waste time

    • Tight pockets where deep sockets help you reach past protruding studs

    How to Use (3 Steps)

    1. Push the nut/bolt fully into the socket until you feel it “grab.”
    2. Start the fastener by hand as much as possible (best practice).
    3. Run it down and tighten with a smooth pull—avoid side-loading to keep the fastener centered.

    Safety Notes

    • Keep the socket fully seated to avoid rounding fasteners.
    • Do not use as an impact socket unless specifically rated for impact use.
    • Follow manufacturer torque specs for critical fasteners.
