Planning Guide

Plan the right fit before choosing

Start With Thread Compatibility

Match the wing nut to the threaded connection

Thread size is the primary selection factor. The represented options include #10-24, 1/4-20, 5/16-18, 3/8-16, 1/2-13, and 3/4-10 sizes. Several products specifically identify UNC coarse threads.

  • Use the same thread designation as the compatible threaded fastener or component.
  • For coarse-thread applications, select products identified with UNC threading.
  • Verify whether your assembly requires #10-24, 1/4-20, 5/16-18, 3/8-16, 1/2-13, or 3/4-10.
Compare Wing Nut Styles

Select the configuration that fits the fastening task

All represented products use wings for hand-operated adjustment. Type A Light Series options are available in #10-24, 1/4-20, and 3/8-16 sizes. A 1/4-20 washer-base option has an integrated washer-based configuration, while other options are standard wing-profile designs.

  • Choose a winged profile for hand tightening and loosening during frequent changes.
  • Choose Type A Light Series when that specified configuration is required.
  • Choose the washer-base design when a 1/4-20 integrated washer-based configuration is needed.
