USS & SAE Flat Washers
Flat washers are often overlooked on worksites, but they play a vital role in structural integrity and product quality. Heavy-duty washers are necessary for machinery repair, facility maintenance, manufacturing, construction, automotive assembly, and many other industrial tasks. At Brazos Fasteners, we’re a trusted SAE and USS flat washers supplier for businesses around the country.
What Are SAE Flat Washers?
SAE stands for the Society of Automotive Engineers. Not surprisingly, SAE flat washers remain popular for automotive applications. They’re also common in general-use applications for commercial and industrial businesses, such as remodeling, equipment repair, electrical, and durable goods manufacturing.
SAE washers have a few distinctive characteristics:
- Narrower thickness (thinner gauge)
- Smaller outside diameter
- Specialized materials (alloy steel, stainless steel, etc.)
You need an SAE flat washer supplier when you’re looking for lightweight, strong, and corrosion-resistant fasteners. These washers get the job done without taking up too much space.
F436 washers are a hardened heat treated steel material that are similar in thickness to the USS pattern washer, but have smaller outside diameters similar to the SAE pattern washer. Typically used in structural and heavier weights and stress applications.
What Are USS Flat Washers?
USS stands for United States Standard. Originally, this fastener rating applied to the U.S. Navy. These days, USS flat washers are common in industrial applications with heavy machinery, such as petrochemical, mining, and off-shore drilling.
USS flat washers offer several advantages:
- Wider OD
- Increased washer thickness
- Larger overall weight
USS-grade washers are especially useful for environments with high vibrations. They offer more load distribution and grip, but you also need wider bolts, such as heavy hex bolts.
