Drilling Screws for Joining Fabric to Metal
 |  |
Attach tarps and fabric to metal surfaces. These screws have an attached, free-spinning washer that stays put as you tighten to prevent bunching the material. They save time by drilling and fastening in one step.
Length is measured from the edge of the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Black-Zinc-Plated Steel—The dark finish withstands occasional exposure to moisture while creating a finished look.
