Required drill bit sizes shown include 3/16" for some high/low thread anchors and 1/4" for others; the correct size depends on the specific anchor type.
One wallboard product is described as a one-piece self-drilling anchor made for hollow gypsum wallboard and intended for light- to medium-duty loads. Other listings note that a pilot hole or pre-drilling is required for secure installation.
The listings show anchors made of plastic or nylon and screws made of steel, with several screws described as zinc or zinc‑plated steel.
Most items describe holding or holding-design features in general terms. One listing includes a numeric note reading "Holds Up to 4000 psi Concrete, 30 lbs," and a concrete screw description highlights an XL washer head for "superior holding power."
Several kits list included screws alongside anchors, and at least one kit description explicitly includes a Phillips installation bit with the anchors and screws.
Pan-head styles are commonly shown for anchors and screws. One concrete-focused screw is described with an XL washer head designed for greater holding power.
