What Are Flange Washer Based Wing Nuts?
Flange Washer Based Wing Nuts are hand-tightened wing nuts supplied with a matching flanged washer. The integrated washer spreads the clamping load over a wider area, helps protect finished surfaces, and makes quick, tool-free adjustment easy on fixtures, covers, and jigs.
Key Benefits of Flange Washer Wing Nuts
- Tool-free operation: Tighten and loosen by hand for rapid set-ups and maintenance.
- Built-in load distribution: Included flange washer reduces surface marring and pull-through on soft materials.
- Fewer loose parts: Paired washer simplifies kitting and assembly.
- Reusable: Ideal for assemblies that are opened and closed repeatedly.
Common Applications for Flange Washer Based Wing Nuts
- Machine guards, access panels, and equipment covers
- Fixtures, jigs, and workholding where adjustments are frequent
- Displays, signage, staging, and lighting rigs
- Furniture and cabinetry knock-down assemblies
- DIY, hobby, and prototype projects
Materials & Finish
Standard parts are made from zamak zinc alloy with a zinc finish for clean appearance and light indoor corrosion resistance. Use in dry, non-marine environments. For higher corrosion resistance, consider stainless wing nuts offered on our Standard Wing Nuts page.
Sizing & Compatibility
Offered in common inch and metric machine-screw threads. Always match the diameter and thread pitch to your bolt or stud (e.g., 1/4"-20, 5/16"-18, M6-1.0). Verify the washer’s outer diameter and thickness provide the bearing area your material requires.
Installation Tips for Flange Washer Wing Nuts
- Start threads by hand to prevent cross-threading; tighten until snug.
- Place the flange washer between the nut and the surface to spread load and protect finishes.
- For vibration, add a split/star lock washer or a medium thread locker on the bolt/stud.
- Avoid over-tightening to preserve threads and maintain easy, repeatable adjustments.
