    Long-Reach Hex Bits That Stay Put on the Fastener

    Built for recessed or hard-to-reach hex fasteners, this 3/8" drive set uses a grip ring to help hold nuts/bolts in place while you guide the socket onto the fastener. The 100mm length gives you reach without stacking extensions, and the 8 common metric hex sizes stay organized on a compact rail for fast selection in the field or shop.

    What It’s For (Quick Guide)

    • Recessed socket-head fasteners where a standard bit socket won’t reach
    • Holding the fastener steady on install/startup (less dropping in tight areas)
    • Faster size selection and cleaner storage (rail keeps the set together)

    Why the Grip Ring Matters

    • Helps retain the nut/bolt while you position the socket on the fastener
    • Useful when you’re working one-handed, overhead, or in confined spaces
    • Reduces time lost fishing dropped fasteners out of guards, pans, or frames

    In the Box

    • 3015M hex bit sockets (100mm long): 3, 4, 5, 6, 7, 8, 10, 12mm
    • Rail (200mm long)

    Safety Notes

    • Fully seat the hex bit in the fastener before applying torque
    • Avoid side-loading the bit (especially on stuck fasteners)
    • Use the correct size to reduce rounding risk
