Value Collection FW5XX01800-050BX M18 Flat Washer 316 Ss

Product Description

The VALUE COLLECTION FW5XX01800-050BX is a standard flat washer designed for use with M18 metric fasteners. Manufactured from Grade 316 stainless steel with a plain finish, this washer delivers strong corrosion resistance in wet, chemical, and marine environments. It conforms to DIN 125A, the widely recognized metric flat washer standard, and measures 19 mm inside diameter by 34 mm outside diameter. It is sold in a package quantity of five. Plumbers, pipefitters, maintenance mechanics, and industrial installers use this washer to distribute load under bolt heads and nuts, protect mating surfaces, and prevent fastener loosening on M18 threaded assemblies.

This washer is suited for general industrial, marine, and commercial plumbing applications where metric fasteners are specified and corrosion resistance is required. Grade 316 stainless steel is preferred in environments exposed to saltwater, chlorinated water, or mild chemical exposure. The DIN 125A form factor is standard in European and metric-specification assemblies, making this washer a direct-fit choice for equipment, pipe flanges, structural connections, and mechanical assemblies that call for an M18 flat washer per that standard.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in marine and chemical environments
• Conforms to DIN 125A metric fastener standard
• 19 mm inside diameter and 34 mm outside diameter for M18 screw fitment
• Plain finish with no coating that could crack, chip, or interfere with torque values
• Sold in a pack of five to support multi-fastener applications

Compatibility

Designed as a standard DIN 125A flat washer for use with M18 metric fasteners in industrial, marine, plumbing, and general mechanical assemblies requiring Grade 316 stainless steel hardware.

Installation Notes

Installation is performed by plumbers, pipefitters, millwrights, or general maintenance mechanics working with M18 metric fastener assemblies. Always verify that the inside diameter clears the fastener shank freely before seating the washer. Use appropriate metric tooling and follow applicable torque guidelines specified by the equipment manufacturer or relevant code. No welding, grinding, or heat treatment should be applied after installation, as this can compromise the corrosion resistance of Grade 316 stainless steel.
