Value Collection FW5X00350-200BX M3.5 Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION FW5X00350-200BX is a standard flat washer sized for M3.5 metric screws, manufactured from Grade 18-8 stainless steel with a plain finish. It measures 4 mm inside diameter by 9.64 mm outside diameter and conforms to DIN 125A dimensional standards. These washers distribute clamp load across the bearing surface of a fastened joint, protecting the mating material and reducing the chance of loosening under vibration. They are sold in a minimum order quantity of 200 pieces per box, making them suitable for production assembly, service stock, and maintenance applications where consistent fastener hardware is needed in volume.

These flat washers are used wherever M3.5 metric fasteners are installed in light mechanical assemblies, electrical enclosures, HVAC equipment panels, plumbing fixture brackets, and similar trade applications. The 18-8 stainless steel construction provides corrosion resistance appropriate for both indoor and moderately wet or outdoor environments. Technicians and assemblers working in plumbing, HVAC, electrical, and general mechanical service will find these washers a straightforward stock item for small-screw fastener applications requiring metric sizing.

Installation Notes

Flat washers of this type are installed by general mechanics, HVAC technicians, electricians, and plumbers as part of standard bolted or screwed joint assembly. Always de-energize electrical panels and shut off relevant system circuits before working on fastened enclosures or equipment. Use the appropriate metric hand tools or power drivers set to a controlled torque to avoid deforming the washer or stripping the mating fastener. Inspect washers for burrs or deformation before installation to ensure proper seating and load distribution.
