    Dome Cap Nuts - 316 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.


    Marine Grade 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. 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

    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 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.
