Technical Features
- Split-ring design: The open, helical split creates spring tension against the fastener and mounting surface, generating friction that resists rotational loosening under vibration and dynamic loads.
- Hot-dip galvanized (HDG) finish: The zinc coating applied through the hot-dip galvanizing process provides corrosion resistance, making this washer suitable for outdoor, exposed, or moisture-prone installations.
- 1/2" sizing: Matches standard 1/2" threaded fasteners (bolts, screws, and nuts), ensuring proper seating and load distribution at the fastener interface.
Applications
- Structural bolted connections in construction and fabrication where fastener vibration loosening is a concern.
- Outdoor and exposed installations where corrosion resistance from an HDG finish is required.
- General mechanical assemblies utilizing 1/2" threaded fasteners that require secondary locking without adhesive or chemical threadlockers.
