5/16-18 Hex Flange Nuts Zinc

Hex Flange Nuts are commonly used in road sign mounting and traffic control installations to securely fasten bolts and hardware assemblies. The built-in flange acts like a washer, helping distribute pressure evenly and reducing the chance of loosening caused by vibration, wind, or roadway traffic.

Typically paired with hex head cap bolts, these nuts are ideal for securing traffic signs, brackets, and mounting hardware to sign posts and support structures. Built for durability and dependable performance in outdoor conditions, hex flange nuts are an essential component for long-lasting roadway and traffic safety installations.
