Description
These HILLMAN Stainless Steel Outdoor Internal Tooth Lock Washers are designed to keep fasteners secure where vibration, movement, and weather threaten to loosen connections. The internal tooth profile bites into the screw or bolt head and the mating surface to resist rotation, making these #8 washers useful for outdoor projects that need lasting hold. Made of stainless steel with a thickness of 0.018–0.023 in, they offer corrosion resistance for exposed applications. With an outside diameter of 0.340 in and an inside diameter of 0.168 in, they fit #8 fasteners commonly used in deck hardware, fence fittings, exterior light fixtures, and other outdoor assemblies. The internal tooth design keeps hardware tight without bulky hardware changes, so repeating maintenance is minimized during routine outdoor use.
