Need some sturdy, rust-resistant bolts for outdoor or heavy-duty projects? This set of 50 carriage bolts with matching nuts is just the ticket. Each bolt is 3/8-16 thread size and 6 inches long, made from strong Grade A 307 steel, and finished with a hot-dipped galvanized coating to fight off rust and corrosion. The round head design sits flush against surfaces, making them great for wood-to-wood or metal-to-wood connections—think decks, fencing, trailers, furniture, or framing. They come with matching nuts so you’ve got everything you need in one pack. Thread style is coarse (UNC), so they grip well and install easily with a wrench or socket. Brand new from Fastenere, sealed in original packaging—exactly like you’d find in a hardware store. Perfect for DIYers, contractors, or anyone tackling outdoor builds. Whether you’re building a swing set, securing a gate, or repairing farm equipment, these bolts are tough, reliable, and built to last.
