Value Collection WY_68025089 M5 Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION WY_68025089 is a standard flat washer sized for M5 fasteners, manufactured from Grade 18-8 stainless steel. It measures 5.3mm inside diameter by 10mm outside diameter and 1mm thick, conforming to DIN 125, ISO 7089, and ISO 7090 dimensional standards. With a hardness rating of 140 HV, this washer distributes clamp load evenly across the bearing surface, protecting the joined material from fastener pull-through and surface damage. Installers use it wherever a corrosion-resistant metric flat washer is required in mechanical assemblies, plumbing, HVAC, or electrical enclosure work.

This washer is suited for general-purpose metric fastening applications in both residential and commercial settings. The 18-8 stainless steel alloy offers reliable resistance to rust and oxidation, making it appropriate for indoor and moderately exposed outdoor environments. It is commonly used by plumbers, HVAC technicians, electricians, and maintenance professionals when assembling equipment, mounting hardware, or securing panels where an M5 fastener is specified.
