Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Material Certificate—Washers include a report with a traceable lot number.
Medium Strength Fastener—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.
