Our carriage bolts, often also referred to as coach bolts, are of the highest quality available, and made of a solid 655 Silicon Bronze alloy. 

Our carriage bolts are partially threaded, with a fully bodied shank and beautifully cut threads, unlike the "carriage bolts" that our competitors carry. The full bodied shank will mean a stronger bolt, and one that will seal nicely in it's clearance hole. As with all of our bronze fasteners, we've carefully chosen our supplier here so that we are only selling the highest quality bronze carriage bolts available.

Round head, square neck.

Meets ANSI/ASME B18.5 Standard Specifications:

ANSI Standards for Carriage Bolts

The formula for determining thread length is: Bolts 6 in. and shorter, 2 diameters plus 1/4 in. Bolts over 6 in. 2 diameters plus 1/2 in. If bolts are too short to apply the formula, the thread will be extended as close to head as possible.

Loved these Bronze carriage bolts. They will be around for very long time

Full Keel Pedigree

The pintles on my sailboat are 1" x 10" 655 bronze rod requiring the same high quality carriage bolts to secure them to the gudgeons. Fairwind Fastners has provided me with these fastners that can stay submerged almost indefinitely. I trust these bolts to keep my rudder in any conditions.

I placed my order and had the bolts the next day. My project was able to continue moving along without interruption. The bolts came in the nicest draw string bags . Nice touch!
Thank you for your quick turn around.

Grand Banks Steering Bolts

I needed four 3/8” bolts, nuts, and washers to replace part of the cable steering system on my 1974 Grand Banks 42. Fair Winds had exactly what I needed. I plan to buy more fasteners in the future. The product quality is excellent.
