Conical Plastic Anchors are injection-molded with a flanged opening at the top end and a cone-shaped body that is cupped at the opposite end. The conical plastic anchor is a light-duty part that can be used in drywall, concrete, hollow block or brick. It is not suited for applications where holding power is important. For use with self-tapping or wood screws.

Machine screw anchors are typically used with light to medium-duty concrete, brick, or block. They require the use of a setting tool, with different diameters requiring different sized setting tools. When installed, force is transferred to the base material. If installed too closely to another anchor, the holding power may weaken.
