Avoid rust streaking down the side of your project and staining all that it comes in to contact with by opting for these 316 stainless steel flat washers instead of the more commonly available 18-8, 304, or A2 Stainless Steels. 

While most retailers won't even carry this more corrosion resistant grade of stainless, it's all we'll sell because we wouldn't use anything lesser ourselves when it comes to fasteners in a corrosive environment. We also like to set ourselves apart by allowing you to purchase these as you need them, and not be held to buying an entire box when only a few will do.

Best stainless steel.

Just got my SS bolts, and comparing them side-by-side with items from big box store L**** the difference is clear. Also I had a great interaction with FW as I made an error in my initial order that was corrected easily. I love the products and love the company.


Yeah, I got a good bit of fasteners Fairwind for my bowsprit. Really like it the way turning out. Just wish the carriage bolts had less thread. I used to get my stainless from various hardware and home emprovement venues with a bit of a question mark. When I purchase from Fairwind...I know I'm getting good quality metal fasteners. Loved the copper nails.
