Extra-Tall Electrical-Insulating Rolled-Collar Sleeve Washers
The extra-tall sleeve extends into holes to provide more protection than other rolled-collar washers. As you tighten your screw, the rolled collar compresses under the head to create an insulating barrier between a screw shank and a mating surface. These nylon washers block electrical current and prevent galvanic corrosion from mating different types of metal. Exposure to moisture may cause them to expand.
