Dottie FWBZ516 Washer, 5/16" Silicon Bronze Flat Washer

Keep critical mounts and enclosures secure with the Dottie 5/16 in Silicon Bronze Flat Washer — engineered to deliver durable, corrosion-resistant fastening for security, surveillance and marine applications. This silicon bronze washer (material: silicon bronze) resists corrosion and high temperatures better than brass, protecting camera mounts, monitoring brackets and network enclosures exposed to salt air or harsh environments. Sized for 5/16 in fasteners and with an outer diameter of 0.89 in, the washer increases fastener surface area to evenly distribute clamping force, prevent bolt pull-through and reduce loosening from vibration — essential for reliable long-term monitoring and security hardware performance. Manufactured to ASME B18.21.1, these washers are intended for use with silicon bronze nuts and bolts in non-critical assemblies and are sold in convenient 100-piece packs to streamline installations. Choose Dottie silicon bronze flat washers when you need marine-grade durability and consistent fit for surveillance mounts, access control hardware, network racks and outdoor sensors.
