Caplugs - Zinc-Plated Finish, Steel, Standard Countersunk Washer

Standard countersunk washers, also known as dimple washers, have a recess that prevents the fastener from splitting or stripping the workpiece material. They are used with countersunk and flathead screws that lie flush against the workpiece.

Steel is strong and durable but less corrosion resistant than stainless steel. To improve its resistance to corrosion, it may receive additional finishes and coatings.
