Split Washer size #2, eight washers per package, zinc-plated, is a compact lock washer designed to help prevent fasteners from loosening in vibration-prone assemblies.

Split lock washers bite into the mating surfaces as the bolt or screw is tightened, creating tension that helps keep the connection secure. The zinc plating adds corrosion resistance, making them a practical choice for hobby projects, RC builds, or other mechanical assemblies. To use, place the washer under the bolt head or nut and tighten as usual to improve retention.
