    Grippers

    Maintain a secure hold on uneven or irregularly shaped parts by clamping against these serrated grippers. All have a through hole to thread a fastener, so they'll stay put for easier alignment than solid-surface grippers.

    Solid-Surface Grippers

    Clamp uneven or odd-shaped workpieces onto these grippers to hold them securely in place. Rather than a through hole, these grippers have a solid surface that grips your workpiece evenly and shields the mounting hole from debris. However, they can be harder to line up than grippers with a through hole. They mount from the bottom with a socket head cap screw.

    Ultra-Fine Serrations—Ultra-fine serrations are the most closely spaced for the lightest penetration of the workpiece.
    Extra-Fine Serrations—Extra-fine serrations are a little farther apart than ultra-fine serrations, so they penetrate the workpiece slightly more for a firmer hold.
