Understanding 1% 202% USS Flat Washer Dimensions and Their Applications

Flat washers are essential components in various mechanical and construction applications. Among the many types available, the USS (United States Standard) flat washer is widely used due to its strength and versatility. This article delves into the dimensions of 1% 202% USS flat washers, their specifications, and their applications in different industries.

What is a USS Flat Washer?

USS flat washers are circular plates with a hole in the center that allows them to be installed over a bolt or screw. The primary function of these washers is to distribute the load of a fastener, prevent damage to the surface, and minimize the risk of loosening caused by vibration. Made from various materials, including steel and stainless steel, USS flat washers are known for their durability and reliability.

Dimensions of 1% 202% USS Flat Washers

When discussing the dimensions of flat washers, several measurements come into play, including the inner diameter (ID), outer diameter (OD), and thickness. The “1% 202%” designation refers to specific sizes that fit certain applications.

1. Inner Diameter (ID) This is the diameter of the hole in the center of the washer. For a 1% USS flat washer, the ID typically matches the diameter of the bolt or screw it is intended to support. For example, a washer designed for a 1% bolt often has an inner diameter close to 1 inch.

2. Outer Diameter (OD) The OD of the USS flat washer is significantly larger than the inner diameter. This larger size allows for better load distribution over the surface area. A common outer diameter for a 1% USS flat washer typically ranges around 2.5 inches.

3. Thickness The thickness of the washer contributes to its strength and resistance to compression. A standard thickness for a 1% USS flat washer may be approximately 0.06 inches. However, variations can exist depending on the specific requirements of the application.

These dimensions are critical when selecting the right washer for a given task, ensuring proper fit and function.
