Dome Nuts (Acorn Nuts) come in two different styles, one-piece and another in a two-piece. A one-piece Dome Nut is constituted from a solid piece of stainless steel. The 2-piece Dome Nut is constituted from 2 pieces of Stainless fused together.

Dome Nuts are on times called as Cap Nuts and Acorn Nuts.

Bolt And Nut Bearing Surfaces Cold-upset bolts are constituted on a “boltmaker” usually consisting of which are washer faced but large or very long bolts may consist of a flat face. Nuts made on cold “nut-formers” may have double-chamfered.

Heat treatment covers numerous techniques that may be utilized to develop certain end-product features. Customary methods for fasteners consist of annealing, stress relieving, case hardening, direct quench and temper, and carbon reconditioning.

Annealing: A thermal cycle constituting heating to, and holding at a suitable temperature which then does cooling at a suitable rate, for such reasons as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure, or receiving desired mechanical or other properties.

Case Hardening: A term derived to describe one or more methods of hardening steel in which the exterior portion, or case, is made considerably harder than the inner portion, or core.

Quenching And Tempering: A thermal procedure utilized to enhance the hardness and strength of steel. Tempering should follow immediately and involves reheating to a temperature below the transformation range and then cooling at any rate desired. When strength necessities are moderate, low-carbon steel is utilized.

Tensile Strength: The utmost tensile pressure is in pounds per sq. in. which a material is capable of balancing, as developed by a tension test.

Yield Strength: The pressure during which a material exhibits a particular divergence from the arrangement of pressure to strain. The departure is communicated in terms of strain, and in the offset technique, mainly, is to strain of 0.2 percent is specified.

Proof  Load: The point to which a material may be emphasized without proof of permanent un proper formation.

Hardness: The refusal to accept of a material to plastic un proper formation. Usually measured in steels by the Brinell, Rockwell, or Vickers indentation-hardness text methods.

All About Cap Nuts Transcript

Note: Below given is the conversation to explain nuts.

Bob: Welcome back to Albany County Fasteners, Fasteners 101. This is Bob and today we’re going to discuss high crown and too tall cap nuts. So let’s get started.
By having cap nuts here. I have a standard cap nut that everyone will find almost anywhere. I have what they call a high crown and you can see, the crown’s a little higher. It’s mostly somewhere about, I would say about, a heavy 3/8 of an inch taller than a standard cap nut. Then we have too tall. We have a too tall in a flat head and we have too tall in a rounded head.
Now the two tall come fully threaded all the way through the inside to the top. So you have full threads all the way through. You have on the too tall what they call a flat top. You can see the top is flat and it has a chamfered edge around it and on the ground, the top is just rounded over like the standard cap nut at the top.
They call these too tool due to they’re approximate, if you took the high crowns, double the height almost. But if you had two high crowns, I don’t have two high crowns here but if I did, it would be close to this size and that’s why they call it a too tall.
These are the USA made products, they’re made here in the USA. They’re quality products.
Depending upon your appliances. So many different appliances out there. How far is your threaded bolt sticking out on the other end? If it was sticking out that much, you couldn’t utilize a standard cap nut.
I’ll just keep my finger there as a stop, and that just makes it. Those are different appliances. This one, which is double tall, will keep on going and, just so you know, you will get some gulling because the difference here with stainless steel is that you have a rolled thread on the bolt and on the actual cap nut you have cut threads. So you have two variant threads running against each other which creates gulling. You can use some lubricant. Which works well.
I just want to show you on this how far this will go in.
As far as appliances go, there are many numerous appliances. I’ve seen these used for – they get polished up – some people will take them and polish them up. Polished stainless is amazing – the way it looks. They’ll take them and put them on their trucks and their cars just for the look. It’s all dependent on the appliances.
Here at my packaging machine, I want to demonstrate to you how they incorporated a cap nut. This is a standard cap nut. This is the bowl where the fasteners go in. This is a feeder and they used a cap nut, at the top, along with a lock washer to hold this cone in place so the fasteners don’t build up and around the center of the machine. Here they used a standard cap nut with a lock washer to hold this cone in place.
You could also, in this application, use any of them. Here’s a high crown, that works on there, and here’s a double tall. You can use that on there. This is actually is a lot simpler due to a few times the small little fasteners that we put in this machine, they get beneath this cone a little bit. They jam below there and you have to prevent this off.
The standard that comes with the machine, you can see here, the standard cap nut, finishes it off nicely.

Applications And Uses Of Dome Nuts –
No matter what industry you work in, you are going to need reliable fasteners in order to achieve your projects. From automobiles to the rockets that we send into space, nothing would be ever achieved without reliable tools and fasteners by our side. While many of us aren’t going to be working on the next spaceship, we still require to know about the different fasteners that are being utilized throughout the world.

Acorn Cap Nuts
Acorn cap nuts are hex nuts with a dome top that matches an acorn nut or crown.
Utilized alone or as a cap for a hex or jam nut, acorn cap nuts serve a decorative purpose by concealing the threaded end of a fastener or acting as a cover for standing out, perhaps sharp threads. Some variants are produced in two pieces and pressed together; others are milled from a single piece of metal. Besides from a possible slight variant in dimensions, both types of cap nut are otherwise the same.
Threads are well measured right-hand and Unified inch stiff series (UNC, Unified National Coarse) or Unified inch fine (UNF, Unified National Fine). Hence these acorn cap nuts constitute a closed-end, the fastener’s projecting threads must be short enough to allow the nut to be fully tightened yet long enough to allow sufficient thread engagement with the nut prominently when utilized alone.
Acorn cap nut size mainly refers to its nominal thread diameter.
Nut width and height differentiate with the size of the acorn cap nut.
Steel, brass and stainless steel are widespread materials. Zinc plating and nickel plating are the most common finishes for steel and brass is often nickel plated.

Dome & Cap Nuts

Trojan Special Fasteners Ltd can produce a number of dome and acorn cap nuts to standard, your drawing, sample or your specification.
Trojan Special Fasteners will produce, from bar turning, high accuracy acorn cap nuts. Other names such as crown hex nuts, blind nuts, cap nuts, dome nuts or domed cap nuts remain.

Dome or cap nuts are probably applied to the threaded end of a bolt, setscrew or all-thread bar.  We regularly furnish polished dome nuts for this reason.
