5/16" Conquest Split Lock Washer - Hot Dip Galvanized

Designed to help keep fasteners tight in tough, outdoor conditions, this 5/16" split lock washer features a corrosion-resistant hot dip galvanized coating. Its spring-loaded helical design bites into the mating surfaces, helping resist loosening caused by movement, vibration, or weather shifts. A reliable option for wood framing, structural brackets, or utility hardware.

Use only with other hot dip galvanized fasteners to ensure performance and corrosion compatibility.
