Carriage Bolts for Woodworking, Construction, and Metal Fabrication
Carriage bolts offer reliable fastening for woodworking, structural construction, and light-to-medium metal fabrication. With a smooth round head and a square neck underneath, the bolts lock firmly into the material during installation. This design prevents rotation and keeps the joint stable even in demanding environments. Because of this secure structure, carriage bolts are commonly used in furniture building, outdoor decking, timber structures, machinery frames, and various industrial assemblies.
Material Options and Protective Finishes
Our carriage bolts are available in carbon steel, stainless steel, and zinc-plated steel. These materials deliver excellent mechanical strength and long-lasting durability. Furthermore, different finishes help protect the bolts from moisture, chemicals, and corrosion. Options include plain, zinc plating, and hot-dip galvanization. With these choices, customers can apply the bolts to both indoor and outdoor projects confidently. Since the smooth head creates a clean appearance, these fasteners also work well in applications where aesthetics matter.
OEM Customization and Flexible Packaging
To support various project requirements, we offer OEM customization for diameter, length, thread type, and coating. Metric sizes and inch sizes are both available. You may also request special packaging such as printed small boxes, plastic kits, or labeled bags. Additionally, we provide free warehouse storage for customers who require multiple shipments throughout the year. This service ensures consistent supply and reduces inventory pressure.
