A Clean, Crafted Finish for Outdoor Builds

The rounded carriage head delivers a neat, unobtrusive accent that lets the wood grain take center stage. I love the tactile, chalky sheen of hot-dipped galvanization—it feels honest and architectural. Use them in rhythmic rows along a fence or garden gate for subtle texture and cohesion. It’s the kind of quiet hardware that elevates everyday structures into refined, lasting design.


Choose these galvanized carriage bolts for a clean look and rust-proof strength on your next outdoor build.

Worked well!
Style: Levelers, Size: 20 Pack
We recently had our first camping trip with our ‘84 RV at a local state park. prior to the camping trip, it had rained a lot. At this park, parking is on grass. I was nervous the heavy RV would sink and we would get stuck so I found these. It was packaged nicely. Easy to figure out how to use. It took a bit to get the RV to back over them but was good once it did. Color is bright. They were stable. A few did “bow” we noticed after we grabbed them out. Came in a nice storage bag and light to carry.

Good product
Style: Levelers, Size: 10 Pack
I am a truck camper that camps about 4 months of every year and use these blocks to level my truck at each of the various sites I camp. They stack and are stored in a bag so take limited space. The blocks are easy to use, quick to deploy, are fairly durable and work well - I love them! They are a little pricy but worth it to me.

Great stabilizer
Style: Levelers, Size: 20 Pack, Style: Levelers, Size: 20 Pack
Very light, seem very sturdy and lock together snuggly. Instead of carrying heavy wood to support, now I can use the light weight levelers. Tested multiple times to make sure they could hold, so far no issues going up and down.
