Zinc-Plated Steel USS Washer
Manufacturer part: 90108A172
These washers meet USS sizing specifications and typically have larger diameters than SAE washers. As a result, they accommodate larger screws and nuts and distribute pressure across a wider surface area. They are also thicker, so they withstand heavier loads and span wider gaps when used as spacers.Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture. Medium Fastener Strength Rating—Rated Grade 5 or Class 8.8, these washers can be paired with medium-strength steel nuts and bolts without deforming. They are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges.For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.
