An anchor rod cap and method for protecting an anchor rod bolt/nut/lower flange assembly are provided. An anchor rod is provided having upper and lower tubular elements connected by a shoulder. The upper element is disposed about the anchor rod threads and has an interior surface defined on a radius smaller than an anchor rod thread outer radius. The lower tubular element has an interior radius larger than an anchor nut outer dimension and is configured to define an air gap between the lower tubular element inner surface and an anchor nut encompassed thereby. A lower tubular element bottom edge is configured to form a physical barrier interface with the anchor rod base flange. At least one of the upper tubular element interior surface and the lower tubular element bottom edge are configured to form a sealing interface with anchor rod thread outer surfaces or an upper flange surface.

Method and structure for an anchor rod cap

A structure and method for a locking nut with a deformable member is provided. The locking nut has an elongated body relative to a comparable standard non-locking nut, allowing the nut to provide a standard length of thread for engaging bolt members while also defining a void for carrying the deformable locking member. The void has a forged side-wall structure that substantially engages the locking member within the void while shipping or handling the lock nut. The locking member deforms and flows into thread areas, thereby providing locking and vibration dampening functions, and also deforms or flows into the side-wall structures, thereby enabling the lock nut to impart sufficient frictional forces to the member to remove the deformed member from an assembly when the nut is removed. The locking forces imparted to the structure by the member may be varied and, therefore, increased by user-applied forces.

Method and structure for locking nut with deformable member

A structure and method for a locknut with a substantially rigid locking member is provided. The locking nut has an elongated body relative to a comparable standard, non-locking nut. The elongated body allows the nut to provide a standard length of thread for engaging bolt members, while also defining a void for the receipt and retention of a removable and replaceable rigid locking member. In a preferred embodiment, the member-carrying void has a forged gear-shaped side-wall structure that substantially engages the locking member within the void while shipping or handling the lock nut, and also causes the member to rotate with the nut as the nut is rotated onto a bolt member, and off of the bolt when loosened. One of either of the bolt threads and locking insert deform responsive to the compressive forces, locking the nut onto the bolt.
