Description
Hillman 1/2-inch SAE flat washers are designed to help strengthen fastening connections by distributing the load of bolts and screws across a wider surface area. By spreading the clamping force evenly, these washers help reduce material damage and improve the stability of mechanical connections. Manufactured to SAE (Society of Automotive Engineers) specifications, these washers are specifically sized for use with 1/2-inch bolts and screws, making them ideal for mechanical assemblies, construction projects, automotive applications, and general repair tasks. Flat washers are commonly used in situations where a bolt or screw head needs additional surface support to prevent pulling through softer materials such as wood, sheet metal, plastic, or composite materials. By increasing pressure distribution, they help improve the overall security and durability of the fastening system. Each washer is constructed from durable steel and finished with a zinc-plated coating that offers moderate protection against rust and corrosion. This corrosion-resistant finish helps extend the life of the washer in general-purpose indoor or light exterior applications. Packaged in a convenient C-Pak containing 50 washers, these fasteners are suitable for contractors, mechanics, builders, and DIY homeowners working on equipment repairs, construction projects, furniture assembly, automotive maintenance, and general hardware fastening tasks. From the Manufacturer Used in applications with nuts and bolts. The flat washer provides a greater bearing surface which helps prevent a nut or bolt head from tearing through the material. Flat washers are commonly used in decks and fence building. The called out size is the inner diameter of the washer.
