Style 7	Style 8	Style 9

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.

Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Super-Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant thumb nuts, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals.

Heavy Duty Wing Nuts

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.

Steel—Best for dry environments since moisture will cause these nuts to rust.

Finish-Your-Own Wing Nuts

Tap your own threads to create a custom wing nut. 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.

Steel—Best for dry environments since moisture will cause these nuts to rust.

18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
