Flanged Wing Nuts
A flange distributes the load over a large area and reduces stress where the nut meets the material surface. The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts. Made from zinc alloy, all resist corrosion in wet environments. Those with a black zinc finish have a dark surface color and offer additional corrosion resistance.

Nylon-Insert Wing Locknuts
These wing nuts have a nylon insert that grips threads to resist loosening. The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts. Made from zinc alloy, they resist corrosion in wet environments.
