Value Collection FWN25513X00300-100BX M3 Fender Washer

Product Description

The VALUE COLLECTION FWN25513X00300-100BX is an M3 fender flat washer manufactured from Grade 18-8 stainless steel with a plain finish. Fender washers are characterized by a larger-than-standard outside diameter relative to the inside diameter, which distributes clamping load over a wider surface area. This washer features a 3.2mm inside diameter and a 14mm outside diameter, making it suited for M3 fastener applications where load spreading or bridging an oversized hole is required. The plain finish retains the natural corrosion resistance of 18-8 stainless steel without additional plating or coating.

This washer is used in metric fastener assemblies across light fabrication, electrical panel work, HVAC equipment assembly, plumbing fixture mounting, and general mechanical applications. The 18-8 stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed. Trades including HVAC technicians, electricians, and plumbers commonly use fender washers when securing sheet metal, mounting control boards, or fastening components to thin-gauge panels where a standard washer footprint is insufficient.

Key Features

• Grade 18-8 stainless steel construction provides corrosion resistance without additional coating
• 3.2mm inside diameter fits M3 screws and bolts
• 14mm outside diameter distributes clamping load over a wider surface area than a standard washer
• Plain finish — no plating or treatment that could flake or interfere with grounding paths
• Metric dimensional system for use in metric fastener assemblies

Compatibility

Designed for use with M3 metric screws and bolts in assemblies requiring an enlarged bearing surface. Suitable for light-duty mechanical, electrical, and HVAC equipment applications using M3 metric fasteners.

Installation Notes

Install using standard hand tools appropriate for M3 hardware. Ensure the washer seats flush against the mating surface before applying final torque to the fastener. When used in electrical enclosures or panel assemblies, verify that the plain stainless finish meets any applicable grounding or isolation requirements per NEC guidelines. Inspect washers for burrs or deformation before installation to avoid damage to mating surfaces.
