Silicon Bronze Carriage Bolts
Couldn't load pickup availability
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:
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.



Order arrived promptly. The bolts are well-made with nice crisp-cut threads! I have ordered Frearson screws from Fair Wind in the past and again, all top notch quality!
I purchased this 10 inch 3/8 inch carriage bolt specifically to mount my bronze anchor roller . It was perfect ‼️. I have not had any disappointment in all my purchases of bronze fasteners from Fair Wind Fasteners. They have been perfect ‼️
Fast service, and just the product I needed. When I forgot a couple items, they called within a few hours to correctly fill my order. I’m very happy.
Great products and great people.
