Silicon Bronze Hex Finish Nuts

Our hex finish nuts are a true, solid 651 Silicon Bronze Alloy and are perfect for securing your bronze bolts. The sizing is perhaps the most commonly used in the world today, and provide adequate strength for most applications.
If heavy nuts are required for your application (recommended on keel bolts for example) they can be found here.
Need an anti-seize and thread protectant for these nuts? Don't forget to add on some Fair Wind Screw Lube.

Fairwinds Fasteners was extremely easy to work with, I identified the quantity, size, and type of fastener, and this was a small, small, order. On the same day as ordered, the product shipped, and within a week, order was received.
Again, very good people to work with! 5 star service.
Customer service was fantastic and they were able to rush ship the parts to us!
Pleasant to deal with.
Had a bit of a hiccup on an order and Rob was super responsive and promt about getting things resolved.
Terrific products, unbeatable service, shipped much faster than I had anticipated. Couldn't be beat!
Needed these parts to finish thru-hull install on my Brewer 44 sailboat. As far as I can tell, these were exact replacements for what were removed. Excellent quality, and prices from Fair Wind on these parts. Thank you for making this job much easier than I thought it would be.
Fast delivery and a good price
Doing some retrofitting of a sailboat with lots of bronze. Fair Wind a great source for quality parts.
