Wing Nuts

Style 1

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.

Plastic

Style 1

Nylon 6/6—These nuts thread on smoothly and resist abrasion to stand up to scratches and bumps. Nylon will swell and weaken when exposed to moisture, so it's best for dry environments.

Nylon-Insert Wing Nuts

The strongest hold of all our thumb nuts. The wings give you extra leverage for a tight fit, while a nylon insert grips the screw to prevent loosening from vibration. However, the insert may become brittle if exposed to high temperatures. You can reuse these nuts a handful of times, but their holding power will decrease with each use.

Zinc

Zinc—Zinc nuts have better corrosion resistance than steel to withstand occasional exposure to moisture. However, they're not as strong.
