Flange Washer Based Wing Nuts

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.

Below are the most-searched questions about flange washer wing nuts, including sizing, materials, vibration tips, and where they work best. Use these quick answers to choose and install the right hardware for your application.

They include a matching flange washer that spreads load and helps protect surfaces, so you don’t have to source a separate washer.

They’re zamak zinc alloy with a zinc finish, best for dry, indoor environments. For marine or harsh chemicals, use stainless wing nuts.

Yes, the flange washer increases bearing area and reduces the chance of impressions. For very soft materials, choose a larger OD washer.

Hand-tightened wing nuts can loosen under vibration. Add a split or star lock washer or a medium thread locker to improve retention.

Common inch sizes (e.g., #10-24, 1/4"-20, 5/16"-18) and metric sizes (e.g., M5, M6, M8). Match diameter and thread pitch to your bolt.

Yes, these are intended for repeated adjustments and reassembly.

Hand-tight until snug; add a small additional turn if needed. Avoid over-tightening to protect threads and finishes.

Absolutely. Ensure full thread engagement and that the washer bears evenly on the surface.

This category features zamak zinc alloy. For stainless options, see our Standard Wing Nuts category or contact us for sourcing.

Typical service temperatures are within normal ambient ranges; avoid continuous high-heat applications that can affect zinc alloys.
