Why Use Wide Washers in RC Aircraft?

Wide washers increase the surface area under the bolt head, helping to prevent crushing, cracking, or loosening of materials like fiberglass, wood, and composite structures. This is especially important in RC aircraft where vibration and repeated stress can cause standard hardware to fail over time.
