USS Flat Washer – Distributes Load, Prevents Damage
Product features
The uss washer is a flat, heavy-duty, standardized washer offered in multiple sizes and materials to fit under the head of a fastener, increasing bearing surface and improving load distribution. Its core function is to distribute load and prevent surface damage so fasteners hold more securely and components resist loosening under vibration. With a thicker profile and larger contact area than thin washers, these durable washers (available in steel, stainless, and plated finishes) provide extended corrosion resistance, longer service life, and reliable performance in construction and machinery applications.
