  • Torque nut having an injection molded breakaway insert
    Patent number: 7775754
    Abstract: A nut having an injection-molded insert or delay stopper is threaded onto an end of an anchor. A capsule containing a resin component and a catalyst component and the other end of the anchor are positioned in a bore hole in a mine roof, mine wall, side of a hill, concrete wall, or concrete floor. The threaded end of the nut contacts the insert and rotation of the nut rotates the anchor, breaking the capsule and mixing the components. After the components set, increased torque is applied to fracture the insert and move the nut up the threaded end of the shaft against roof stabilizing components on the shaft.
