Key Features

• Genuine OEM Hardware Grade — Manufactured to Multiquip's exact material and dimensional spec, ensuring the washer distributes load correctly without deforming under torque.
• Exact-Dimension Replacement — The 3/8 x 1-1/4 sizing matches the original fastener layout precisely, dropping into place without rework or re-drilling.
• Broad Water Trailer Compatibility — Confirmed fitment across WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, and WT5HPSG Water Trailer variants.
• Structural Load Distribution — The wide fender profile spreads clamping force across a larger surface area, protecting mounting panels and frames from stress cracking over time.
• Corrosion-Resistant Construction — Built to hold up in the wet, outdoor environments that water trailers operate in, resisting surface degradation that can compromise fastener integrity.

A fender washer is a large-diameter flat washer used with a standard bolt or screw to spread the clamping load across a wider surface area than a standard washer. On water trailer equipment, this is especially important at panel joints, frame attachments, and cover fastening points where the material being clamped is relatively thin or soft. When a fender washer is missing, undersized, or corroded through, the bolt head or nut can pull through the mounting surface, causing panels to loosen, rattle, or fail structurally. Replacing a worn or damaged washer with the correct OEM part restores the integrity of the connection and prevents progressive damage to surrounding hardware.
