The DAYTON PARTS 0.88" x 1.50" x 0.11" flat washer provides a stable surface to efficiently distribute load across the joint. It reduces friction between the bolt and installation surface by minimizing wear and damage through effective pressure distribution. The flat design also prevents loosening by ensuring even pressure across the surfaces. In environments subject to high vibration, this washer protects surfaces from direct contact, offering consistent and reliable performance, thereby preserving the integrity of the joint over time.
