Frequently Asked Questions

What materials are carriage bolts commonly made of?

Carriage bolts are commonly manufactured from materials such as carbon steel, stainless steel, and sometimes brass or aluminum. Carbon steel bolts are cost-effective and widely used for general-purpose applications where corrosion resistance isn’t a primary concern. Stainless steel carriage bolts, including 304 and 316 grades, offer excellent corrosion resistance, making them ideal for outdoor or wet environments. Brass and aluminum options are chosen for their non-magnetic properties or lightweight characteristics, respectively.

customer evaluation

Mark Johnson

I used these carriage bolts for a wooden deck project, and they worked flawlessly. The square neck design prevented the bolts from spinning when tightening the nuts, which was a huge time-saver. The rounded heads sit nicely against the wood surface, creating a smooth finish without any snagging. I chose stainless steel ones for outdoor use, and after six months of exposure to rain and sun, there's no sign of rust. The bolts held the deck boards securely even during heavy storms. Highly recommend for woodworking projects where both functionality and aesthetics matter.
