Metric Dome Cap Nuts - A2 Stainless Steel
Hex Nuts with a Domed Top to Cover Exposed Threading
Acorn nuts are a type of fastener whose name comes from its shape. It is a hex nut with a closed-end, domed top to cover the exposed threaded end. They are also known as cap nuts and dome nuts. Acorn cap nuts are easily removed for maintenance to be performed. They also provide an aesthetically pleasing finished look. Acorn Nuts are available in 304/18-8 Stainless Steel, 316 Stainless Steel, Brass, Chrome Plated, and Nickel Plated finish.
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.

What is a cap nut used for?
Acorn Cap Nuts are used to cover the exposed threading of threaded rods or studs and bolt ends. This is done for safety reasons and to provide a clean, finished look to the application.
How do you remove a cap nut?
Removing a cap nut is simple. They're threaded the same way as traditional hex nuts, so they can be removed with traditional pliers, wrenches, or ratchets that fit snugly around the nut.
How do you install a cap nut?
Same as other hexagonal nuts: with a wrench, pliers, or a ratchet. Cap nuts are just hex nuts with a dome over one side of the internally threaded hole, enclosing it.
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.
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.
