Marine Grade Wing Nuts in 316 Stainless Steel
Easily Installed and Removed by Hand
Wing Nuts feature two protruding wings on either side of the nut to tighten or loosen by hand. Wing Nuts are commonly seen on assemblies that require adjustment or are not permanent. They are also used when convenience is a driving factor.
Stainless Steel
18-8 or 304 grades of Stainless steel are suitable for many general purpose applications, especially freshwater and non-salt water wet environments. Corrosion-resistant and durable, 18-8 stainless steel is equivalent to the A2 grade of stainless steel.
For much more corrosive environments, such as in saltwater or marine applications, 316 stainless steel is the ideal choice. 316 Stainless steel is equivalent to A4 stainless steel.

FAQs
How is a wing nut designed to be tightened?
Wing nuts are designed to be tightened with your fingers. They can also be tightened using special wing nut drivers that are compatible with power tools.
How do you use wing nuts?
Wing nuts should be used in applications where the workpiece needs to be frequently changed or moved.
What is a butterfly nut?
A butterfly nut is a nut with wing-like protrusions on either side, intended to be fastened by hand. It's another name for a wing nut.
What is stainless steel good for?
Stainless steel is good for general purpose applications, especially those involving water or freshwater. Suppose you need stainless steel for more corrosive environments, such as marine or salt-water applications. In that case, we recommend the 316 grade of stainless steel.
What does 316 mean for stainless steel?
316 is a grade of stainless steel under the 300 series of stainless steel, including 303, 304, and 305. 316 Stainless Steel is distinct from these other grades because it is highly corrosive resistant and well suited to marine applications.
Is 304 or 316 stainless better?
316 stainless steel is better in most ways over 304 stainless steel. 316 Stainless has excellent corrosion resistance, strength, and hardness and is well suited to marine applications. However, it's much more expensive than 304 and is not as formable as 304 either.
Can I use stainless steel nuts with bolts of a different metal?
Depends on the material. Some materials, such as zinc plated steel, are safe to mix with stainless steel. However, aluminum is not safe to use because it risks galvanic corrosion of the materials. We recommend keeping like-metals together in applications.
