These acorn nuts (often called cap nuts) are 655 Silicon Bronze alloy and machined in the USA. They're great for capping off keel bolts, finishing visible bronze knees, or for any other purpose where aesthetics are important. They come un-polished, but polish up very easily.
Other sizes not listed here are available in any of our fasteners. Just get in touch if you can't find the size or type of fastener that you need.

Need an anti-seize and thread protectant for these nuts? Don't forget to add on some Fair Wind Screw Lube.

I got my beautiful bronze cap nuts and washers right on time and for such a fair price. Thanks, Fair Wind. I'll be back.
Along with the acorn nuts, I bought the other fasteners needed to mount the license plate and frame to my trike. It's an anniversary edition, so it's finished with bronze accents, and good bike feng shuei (!) dictated a little creativity with a couple cans of spray paint and these acorn nuts.
The finish on them matches the emblems perfectly, and it ties everything together.
Boat stuff on a bike, yep!
Thank you

Silicon Bronze Acorn Nuts
This is my go to spot for fastners!
Very happy with the fast shipping, care in packaging, and especially the quality of the bronze screws and nuts. And with all this, prices comparable with much lesser quality parts from other sources.
Good. Fairwind Fasteners always delivers-and promptly too!
I am very pleased with my purchase. I received my order quickly, the quality is very good, and it highlights my propeller mounting project beautifully.
Great
I used some washers and acorn nuts to cover some wedge bolts on a light backplate. This is a house that’s near the ocean so we wanted top notch grade on our washers and acorn cover nuts. They look amazing! Top quality.
I was impressed with the quality and delivery time.
