Wide outer diameter for maximum bearing surface; zinc plated for corrosion resistance.
Standard fender washers are designed with an extra-large outer diameter to provide a greater load-bearing surface. They are commonly used to prevent pull-through in sheet metal and soft materials. These washers are ideal for use in plumbing, electrical, automotive, and general-purpose fastening where oversized holes or material softness are a concern. The zinc-plated finish enhances durability and offers rust protection, making them a reliable choice for both indoor and outdoor applications.
