Hard to find square nuts in 655 Silicon Bronze alloy, and we have them here at Fair Wind Fasteners!

Beautifully machined, and will look great on your application. Square nuts have a larger surface contact area than standard hex nuts. The machined edge chamfers both front and back making this a true square nut, as famously used on Hereshoff vessels but also used all over in the traditional boat building world.

Your square nuts will come un-polished, but they do polish up to a gorgeous shine just like any of our silicon bronze hardware.

 Size Width across the flats (inches) Width across the flats (mm)
1/4-20 0.432" 10.98mm
5/16-18 0.558" 14.15mm
3/8-16 0.610" 15.51mm
1/2-13 0.790" 20.06mm
Fair Wind Screw Lube

 

 

Don't forget to add some Screw Lube to protect the threads on these nuts against galling and corrosion, making them easy to undo years later.

Great Service

I ordered the wrong size fin-bolts by mistake. I contacted Rob the next day, and he cancelled my order and refunded my payment. I then ordered the proper size, and my order was sent out that day. In my experience, it is rare today to be able to contact someone at an on-line vendor. It is even more rare to get an immediate answer from an on-line vendor. Thank you Rob.

One of a kind!

Fairwind carries beautiful yellow bronze fasteners I"ve been unable to find anywhere else especially in the larger sizes. They even threw in a couple carpenter pencils and floating key chain which was cool!
