Flat Washers with a Greater Thickness that Standard Washers
A Flat washer is a round outer diameter thick plate with a center hole (inner diameter) punched to the size of the bolt or screw size. Flat washers are normally used to distribute loads of threaded bolts, screws and nuts evenly as the fastener is tightened. These extra thick flat washers are used in decks, docks and large timber projects. They add extra support to a fastener setup and are likely to reduce the risk of damaging the fastened material. Extra thick flat washers can handle the strength of a stronger fastener.

Bob: Welcome back to Albany County Fasteners - Fasteners 101. I'm Bob and today we're going to discuss washers. Let's get started.
What I have here are extra thick washers. I have a standard stainless steel washer here, you can see, the thickness of the two different washers. I'm going to try to do this as best I can for you, but you can see here, the difference in thickness. This one here is a standard washer thickness and this is a extra thick stainless steel washer. So you can see the substantial difference. That's probably almost 2-1/2 - 3 times the standard washer. The extra thick washer is.
They also are available in fender washers.
So again, they're about two to three times as thick - the extra thick washers. We also have them in grade 8, SAE, extra thick. You can see the difference: between this is the standard and this is the extra thick and in that situation it's definitely three times not two and a half time like the stainless, but like three times thicker than the standard SAE flat washer.
