I need 12 brass acorn nuts metric sizeM8 1.25 Do you have any? If so, how much ?
Please check with Jamestown
Does it mean you do not carry these metric brass acorn nuts in size 8?
I cannot answer this question.
What is the thread depth (height) of the 1/2-13 brass cap nut?
The nuts were about 1/2" in size. Not sure about the depth, sorry. I bought them at the request of someone else, but i know they worked out perfectly. Sorry couldn't be of more help.
Tom:The brass Acorn Nuts I purchased 1/4" X 20, however the proportion of the usable thread depth and depth of the inside dome from the face of the nut should be comparable. Your measurements would be twice those of the 1/4' nuts shown below.....1/4" brass acorn nut measures.280 inch of usable thread inside of the nut..350 inch of space from face to the inside of the dome.
The depth of thread is about the diameter as I recall. So for a 1/2" nut you will get 1/2" of thread.
I am looking for an 8-32 Brass Acorn Nut. I am trying to match some existing acorn nuts that have an outside dimension of 3/8 of an inch. Can you tell me what the outside dimension is?

Hi! I just went out to our garden railroad and measured the brass acorn nuts as it was getting dark. I brought the ruler in and looked at it in a good light and I would say the outside measurement is 5.5 sixteenths of an inch. So it is a hair under 3/8ths of an inch. David
I bought much larger nuts for a 5/16" bolt, so I am not sure about the dimensions of the #8-32. From what I can tell, the brass nuts are identical in size to the stainless nuts - same socket size. So if you now have plated or stainless acorn nuts that are the size you want, I believe the brass nuts will be the same.By the way - the machining quality of this supplier was excellent - I ended-up polishing and lacquering the nuts and washers to maintain the beautiful finish.
Why don't you show the thread sizes in the product description?

The last numbers in the product description are threads...For example, FBRAN832 8-32. is a #8 w/ 32 threads per inch.
I use these for decorative caps in the construction of wood-gear clocks. The previous reviewer is correct in saying that these are not well finished and not "decorative" [...]. They are, however, solid brass, so I spin them on a threaded rod in the drill press and polish them with fine abrasive paper and Nevr-Dull, after which they look fine.
Not very "decorative"
These acorn nuts are perfectly functional, but for a part with a decorative purpose, they are lacking. I had to spin them in a drill press and polish them with grades of sandpaper and Never-Dull to make them presentable on a wooden clock frame.
I will definitely use Jamestown as a source of my supplies.
Don't trust the photo
The example photo shows a nice crown on the acorn nut. However, the actual crown looks like they have all been flattened with a hammer. I was looking more for an aesthetic look rather than an industrial look. Will not order these again unless I can get what the photo actually looks like.
