5mm Flat Washer (20/Pack)

Metric Flat Washers are made from medium carbon steel, tempered and zinc plated. Best for areas where high strength is desired
• Zinc plating offers moderate protection against rust and corrosion
• Designed for use specifically with USS threaded bolts
• Prevents a nut, bolt, or screw of the same finish and size from pulling through material
• Parts are coated with zinc for a corrosion-resistant finish
