Value Collection WY_68025360 M18 Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION WY_68025360 is an M18 standard flat washer manufactured from grade 18-8 stainless steel. It is designed to distribute load evenly under a bolt head or nut, reduce surface damage, and prevent fastener pull-through in assemblies subject to corrosion exposure. With an inside diameter of 19 mm, an outside diameter of 34 mm, and a thickness of 3 mm, this washer meets DIN 125, ISO 7089, and ISO 7090 dimensional standards. A hardness rating of 140 HV provides adequate resistance to deformation under typical clamping loads. Plumbers, pipefitters, marine technicians, and general mechanical tradespeople commonly use washers of this type in stainless fastener assemblies.

This washer is suited for metric fastener applications where corrosion resistance is a priority, including marine environments, food-processing equipment, HVAC ductwork connections, plumbing fixtures, and outdoor structural assemblies. Its M18 screw size fits standard M18 fastener hardware. The 18-8 stainless steel alloy offers good resistance to rust and mild chemical exposure without requiring additional coating or plating. This is a metric-dimensioned component conforming to widely recognized international fastener standards, making it appropriate for both OEM manufacturing and field service replacement work.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 19 mm inside diameter sized for M18 fasteners per DIN 125 and ISO 7089 and 7090 standards
• 34 mm outside diameter provides broad load-bearing surface to protect mating material
• 3 mm thickness delivers rigidity without excessive stack height
• 140 HV hardness rating resists deformation under standard clamping loads
• Metric system of measurement; conforms to internationally recognized fastener standards

Compatibility

Designed for use with M18 metric fasteners in assemblies requiring standard flat washers per DIN 125, ISO 7089, or ISO 7090 specifications.

Installation Notes

Installation is performed by any trade professional working with M18 metric fastener assemblies. Verify that mating fasteners and nuts are also grade 18-8 or compatible stainless steel to avoid galvanic corrosion between dissimilar metals. Torque fastener assemblies according to the equipment manufacturer's specifications for M18 hardware. Inspect washers for deformation or surface damage before reuse in critical structural joints.
