    The easiest nuts to twist on and off by hand, these are commonly used to fasten parts that need to be frequently disassembled, such as access panels and covers. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
    Black Corrosion-Resistant-Coated Steel—Combines a finished appearance with the rust resistance of stainless steel. The coating has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments. Also known as black luster.
    Steel—Best for dry environments since moisture will cause these nuts to rust.

    Heavy Duty Wing Nuts
    3D CAD models available

    These rugged nuts have a taller base than other wing nuts with more threads to engage for a better hold. They also have a thicker body so they won’t weaken under high stress. Strong enough for use on tanker trucks, they are designed for large, heavy assemblies that need to be opened and closed often. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

    Low-Profile Knurled-Head Thumb Nuts
    3D CAD models available

    Twist these thumb nuts into spaces without a lot of clearance. They have a short, slip-resistant head, so you can grip them easily and make controlled adjustments in cramped spots. You can also use them as jam nuts by threading them against another nut to hold it in place.
