Four arms and an extended tip help you guide these screws into holes with greater control. The arms of the head have more surface area to grip than knurled-head thumb screws. The extended tip acts like a dowel—it fits into mating holes, aligns and holds parts together, and prevents cross-threading. Use these screws for workpieces that you regularly reposition or align. Also known as dog-point and pilot-point thumb screws.
Length is measured from under the collar.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
