Spirol® Dowel Bushings provide precision alignment of mating components and shear-load protection for the bolt when installation guidelines are followed. Their hollow design permits a fastening screw or bolt to pass through the controlled inside diameter into a threaded component, isolating the bolt from shear loading and increasing joint integrity without the need for separate bolt holes. They have lead-in beveled chamfers to ease insertion and prevent skiving of the bushing during installation.
