Universal 3/16" Fender Washer | Zinc-Plated Wide Bearing Surface | 1183
✓ In stock
Zinc-plated steel fender washer for 3/16" fastener applications. The oversized outer diameter of a fender washer distributes clamping load across a much wider area than a standard flat washer, preventing pull-through and crushing when fastening into thin sheet metal, plastic panels, or soft materials. Ideal for body panel repairs, trim attachment, and sheet metal fastening.

What is a fender washer and how is it different from a standard washer?
A fender washer has a much larger outer diameter relative to its inner hole size compared to a standard flat washer. This extra bearing surface spreads the clamping load of a bolt or screw over a wider area — critical when fastening into thin sheet metal, body panels, or plastic where a standard washer would allow the bolt head to pull through.
When should I use a fender washer in automotive work?
Use a fender washer when attaching trim panels, brackets, or hardware to thin body sheet metal; when repairing elongated or oversized holes; when securing soft materials like foam or rubber; or any time you need extra pull-through resistance beyond what a standard washer provides.
What does zinc plating do for a washer?
Zinc plating provides a corrosion-resistant coating on the steel washer, preventing rust in moisture-exposed locations such as rocker panels, underbody attachments, and exterior trim. Zinc-plated washers are the standard choice for automotive body and trim applications.
Can I use these washers with rivets?
Yes. Fender washers are frequently used as backing washers on the far side of a riveted joint in thin sheet metal, providing additional pull-through resistance around the rivet hole. Ensure the inner hole of the washer is appropriate for the rivet shank diameter being used.
What pack sizes are available?
Available in packs of 100, 200, 300, and 400 to suit individual repairs or shop stock needs.
