Browse Our Carriage Bolts

When you're working on a build that deserves more than hardware-store basics—whether it’s a timber frame, custom gate, or heirloom furniture—carriage bolts offer the perfect blend of strength and style. But not all carriage bolts are created equal. From head shapes to finishes and thread styles, the type you choose can affect both the function and final look of your project.

At Old West Iron, we offer a wide variety of carriage bolt types designed to match the rugged authenticity and performance you expect from traditional ironwork.


5/16" Dia. Carriage Bolt - Smooth


Round Head Carriage Bolts

This is the classic design most people think of when they hear “carriage bolt.” These bolts have a smooth, domed head and a square shoulder beneath the head that locks into the material and prevents spinning.

✔ Ideal for: timber framing, doors, and exposed joinery
✔ Available in: raw, black, sealed, or distressed finishes
✔ Pro tip: Use with a decorative washer for added visual impact


3/8" Dia. Distressed Flat Head Carriage Bolt


Flat Head Carriage Bolts

Our distressed flat head carriage bolts offer a more subtle, flush appearance—perfect for applications where a low profile is needed but you still want the aged character of forged iron.

✔ Ideal for: furniture, cabinetry, and places where the bolt head shouldn’t protrude
✔ Finish options: black powder coat, raw iron, antique patina
✔ Aesthetic: clean yet rustic


3/4" Dia. Carriage Bolt - Hammered Texture


Decorative & Hammered Head Bolts

For projects where visual detail matters, choose a carriage bolt with a hammered or hand-textured head. These bring out the character in rough-sawn beams, rustic gates, or antique-style hardware layouts.

✔ Ideal for: restoration work, vintage builds, or projects with exposed hardware
✔ Each piece has unique texture from hand-forging
✔ Matches beautifully with our clavos and square nuts

Thread Options: Fully vs. Partially Threaded

At Old West Iron, we offer both fully threaded and partially threaded carriage bolts. Not sure which you need?

  • Fully threaded bolts offer more flexibility and are ideal for thinner material or through-bolt applications.

  • Partially threaded bolts provide stronger shear strength, which makes them ideal for load-bearing joints in timber construction.

Need help choosing? Just ask—we’ll help you select the right thread style based on your project’s specs.
