Carriage Bolt Advantages

Carriage bolts are best known for their smooth, rounded head and square neck. The square neck prevents the bolts from turning while tightening. The smooth head style makes carriage bolts an excellent choice for fastening surfaces that need a clean, finished look. Additional carriage bolt benefits include: 

• Self-locking design: The square neck digs into the material, preventing the bolt from spinning during installation.
• Enhanced safety design: The smooth, domed head removes sharp edges, making it safe for public use.
• Increased aesthetics: A clean, flush finish provides a more professional and visually appealing appearance.
• Corrosion-resistant: Available finishes like hot-dip galvanized and zinc-plated provide a protective layer against rust.
• Strong, secure fastening: The full threads and durable carbon steel construction ensure a tight and reliable connection.
• Cost-effective: These versatile fasteners are an economical choice for a wide range of projects.

If your project requires a clean finish look but with a larger head diameter, consider our selection of elevator bolts. We offer carriage bolts in grade A and grade 5 steel with various finishes, including metric and even stainless steel. Do not forget to add the supporting hardware, nuts, and flat washers to your cart!
