Spring alignment dowels in the SD200 series are roll-formed, hardened steel components designed to accurately locate mating components, eliminate separate bolt holes, and protect fasteners from shear loading by isolating tension forces. They feature a spring action staggered seam for self-retention after installation, lead-in chamfers to ease insertion, and a controlled inside diameter to accommodate bolts. Dimensional data is provided for metric sizes, with nominal dowel diameters ranging from 6 to 12 mm and standard lengths of 12, 15, 20, 25, and 30 mm. Single shear resistance ranges from 6.6 kN to 27.1 kN depending on size. Inch sizes are available upon request, with all dimensions applying prior to plating for special orders.
Spring alignment dowels are used to accurately locate components with respect to each other. They are formed around arbors to assure roundness. It is recommended that one half the hole tolerance be used for the fixed location of the dowel and one half for the hole in the mating part.
