Elastic dowels - Import export

SPIROL’s Dowel Bushings and Spring Dowels are designed to maintain alignment and are used to locate components with respect to each other. These roll-formed, hollow Alignment Dowels have lead-in chamfers that facilitate insertion into the holes of both mating components. The Dowel's flexibility enables absorption of wide hole tolerances and the staggered seam prevents interlocking. Dowel Bushings are designed with an inside diameter clearance that allows the passage of a bolt for fastening, thereby eliminating the need to drill an additional hole. They are also heat treated to isolate the bolt from shear loads.
