    Hold Nuts and Bolts Securely Without Magnets

    Hold Nuts and Bolts Securely Without Magnets

    Ko-ken’s NUT GRIP® design helps hold non-magnetic nuts/bolts firmly inside a 6-point socket—so you can start fasteners and work in awkward positions with less fumbling. The retention system uses two balls held by a spring steel ring, creating a secure “grab” on the fastener without relying on a magnet.

    What This Tool Is For

    • Starting nuts/bolts in tight or hard-to-see areas where dropping a fastener wastes time

    • Working with non-magnetic fasteners where magnetic sockets don’t help (NUT GRIP® holds without magnets)
    • General shop work needing secure fastener retention during removal and reinstall

    Key Features That Matter

    • Non-magnetic retention system (two balls + spring steel ring) helps keep fasteners from falling out
    • 6-point socket design for strong contact on fastener flats
    • Organized on a rail for quick size selection and inventory control

    In the Box

    • 1x Socket rail

    • 11x 3/8" drive NUT GRIP® sockets (3441M): 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19mm

    How to Use (Quick Steps)

    1. Select the socket size and press it fully onto the fastener.
    2. Let the NUT GRIP® retention hold the nut/bolt as you guide it into position (no magnet needed).
    3. Once the fastener is started, run it down normally and torque to spec.

    Safety Notes

    • Wear approved eye protection.

    • Always seat the socket fully before applying torque.
