XunLiu 316 Stainless Steel Flat Washers 50-Pack M6 (M6X18X1.6mm)
Why Choose 316 Stainless Steel Over 304? Most low-cost washers use 304 stainless steel, which can pit and corrode when exposed to saltwater or chlorinated environments. XunLiu's washers are crafted from 316 stainless steel, which contains molybdenum — a key element that dramatically improves resistance to pitting corrosion, salt spray, and harsh chemicals. Whether you're rigging a sailboat, building outdoor furniture, or maintaining industrial equipment, these M3.5 flat washers distribute load evenly, reduce surface damage, and provide a secure, long-lasting connection. The smooth matte finish ensures clean installation without scratching hardware. Available in 30 sizes (M1.6 – M30) and multiple quantity packs, so you can stock up exactly what you need for any job, big or small.
