Wing Nuts


Style 1	Style 4	Style 5	Style 7	Style 8

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

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

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.
