    With a domed head, these screws add a finishing touch to brackets and architectural applications. With only two contact points, it's best to hand tighten the slotted drive instead of using power tools.

    Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from the top of the head.

    Zinc-Plated SteelA common choice for areas with occasional exposure to moisture.
