---------Bonnell Spring

    As we all know, Bonnell springs need to be connected in steel wires by the specific assembly machine.

    However, due to the characteristics of steel wire, it is easy to rust, and if the pressure is too heavy, it will be squeezed and deformed, causing damage to the bed core.

    Therefore, we recommend adding a frame around the spring bed cores, which will make the structures of the bed cores much stronger.

    Due to the structural problems of the Bonnell spring, we use specially shaped nails to firmly fasten the springs and frame steel wire.

    Our guns and nails have two different types, which are continuous and normal type.

    Here shown are the normal types:

    These are continuous types:

    Our finished bed core frame is shown below.

    If you want to buy this kind of nail, you need to tell us the diameter of your frame wire and the diameter of the bed core wire so that we can give you the exact size.

    Also, if you use edge guard support springs, please also kindly offer their diameters.

    If you are interested in purchasing or know, please come to us for consultation at any time.
