Roll formed hardened Spirol® Spring Dowels accurately align mating components with respect to each other. They are formed around arbors to assure roundness, have staggered seams to prevent interlocking, and lead-in beveled chamfers ease insertion. Their outer diameter is larger than the diameter of the mounting hole, and their spring action enables them to conform to a drilled or cored hole and be self-retained.
