UNITARY CARRIAGE BOLT

摘要

A unitary carriage bolt that has nibs that will counter sink into a work piece to prevent rotation of the carriage bolt. As the nut of the unitary carriage bolt is tightened down the nibs are forced into any malleable surface. Once the nibs are totally counter sunk into the work piece the unitary carriage bolt cannot be rotated. The nut must first be loosened enough for the nibs to be removed from the work piece before it is rotational.
