    Shims for D-Profile Shafts

    Image of Product. Front orientation. Shims. For D-Profile Shafts, Sold Individually, Round.
    With a partially flat inside surface, these shims won’t spin out of position to precisely align and space components on D-profile shafts and arbors.
    You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.

    D-Profile Shaft Collars

    Image of Product. Front orientation. Shaft Collars. D-Profile Shaft Collars.
    Slide these collars over the end of a D-profile shaft and tighten the clamping screw. They grip both the flat and round surfaces evenly without marring the shaft, so you can reposition or remove collars later.
    Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
    Aluminum—One-third the weight of steel and corrosion resistant.

    Shim Assortments for D-Profile Shafts

    Image of Product. Front orientation. Shims. Round, Sold as Assortments, For D-Profile Shafts.
    When you don’t know the exact shim thickness you’ll need, keep multiple shim thicknesses on hand so you always have the right one. With a partially flat inside surface, these shims won’t spin out of position to precisely align and space components on D-profile shafts and arbors.
    You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.
