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.
