Dottie FWBZ58 Washer, 5/8" Silicon Bronze Flat Washer

Ensure reliable, corrosion-resistant fastening for security and marine applications with the Dottie 5/8-inch Silicon Bronze Flat Washer. This Dottie washer increases the bearing surface of bolts and screws to prevent pull-through and spread clamping force evenly across mounting surfaces — critical for surveillance cameras, monitoring equipment, and other security hardware. Made from durable silicon bronze, the washer offers superior corrosion resistance and elevated temperature tolerance compared to brass, making it suited for harsh outdoor and marine environments. The washer measures approximately 1.78 in OD (sized for 5/8-inch fasteners) and is supplied in a convenient pack of 25 for efficient installation and inventory control. Manufactured to ASME B18.21.1 standards, it pairs best with silicon bronze nuts and bolts for non-critical yet demanding applications. Use these flat washers to reduce vibration-related loosening and extend service intervals on camera mounts, conduit supports, and other low-voltage or networking fixtures. Order a pack today to protect your next security or marine installation and keep monitoring systems performing reliably.
