Carriage Bolts: Manufacturer, Types, and Standards

Introduction

Carriage bolts are extensively utilized across industries such as construction, automotive, and furniture manufacturing. Known for their smooth, rounded head and square or ribbed underside, carriage bolts offer excellent holding power and are designed to be used in applications requiring a secure fit with wood or metal. This blog provides an in-depth look at carriage bolts, including their types, applications, key manufacturers, and relevant standards.

Types of Carriage Bolts

Carriage bolts come in different types, each designed for specific applications. Below are the common types of carriage bolts:

1. Round Head Carriage Bolts

The most common type of carriage bolt.

Features a rounded, domed head that offers a clean, finished appearance.

Used mainly in wood applications where aesthetics are important.

The head provides a smooth surface for tools like a wrench or socket to grip.

2. Flat Head Carriage Bolts

Designed with a flat head rather than a rounded one.

Perfect for applications requiring a smooth, flush finish.

Often used in metal-to-metal connections, such as securing metal components.

3. Elevator Bolts (Modified Carriage Bolts)

A variation of the carriage bolt with a larger, dome-shaped head.

Commonly used in elevators and machinery applications.

Offers increased durability and a wider surface area for greater clamping force.

4. Square Neck Carriage Bolts

Features a square neck just below the head.

Provides better grip and reduces the chance of the bolt turning when tightened.

Ideal for wood applications, ensuring a secure connection.

Carriage Bolt Manufacturers

Several manufacturers are known for producing high-quality carriage bolts. Some of the prominent ones include:

Carriage Bolts Standards

Carriage bolts are manufactured to comply with various international standards to ensure quality, performance, and safety. The primary standards that apply to carriage bolts include:

1. ASTM A307

Specifies the standards for carriage bolts, ensuring their suitability for structural applications.

Covers materials like carbon steel and ensures mechanical properties such as tensile strength, hardness, and elongation.

2. ANSI/ASME B18.5

Specifies the dimensions, tolerances, and thread requirements for carriage bolts.

Provides guidelines for proper threading and dimensions to ensure compatibility with tools and other fasteners.

3. ISO 4014 and ISO 4017

International standards for hexagon bolts, which include some specifications relevant to carriage bolts, especially in metal-to-metal applications.

Ensure quality and uniformity in terms of threading and head dimensions.

4. DIN 603

A European standard similar to ASTM A307, focusing on square-neck carriage bolts.

Used extensively in Europe for various industrial applications, especially in construction.

Applications of Carriage Bolts

Carriage bolts are versatile and find extensive use in various applications due to their unique design features:

1. Construction

Commonly used in structural applications such as connecting wood or metal parts.

Ideal for wood framing, decking, and structural supports due to their ability to hold securely in wood.

2. Furniture Manufacturing

Frequently used to assemble wooden furniture components.

The rounded or flat heads provide a smooth finish and reduce the risk of damaging the material.

3. Automotive Industry

Utilized in automotive manufacturing for securing metal parts to vehicle frames.

Offer enhanced clamping force, ensuring durability under vibration and stress conditions.

4. Machinery and Equipment

Used in machinery, especially those requiring vibration resistance and load-bearing capabilities.

Ensure that metal parts are securely fastened and reduce loosening due to operational stresses.

Benefits of Carriage Bolts

Carriage bolts offer numerous benefits, making them a top choice for a wide range of applications:

Secure Holding Power

The square neck design locks the bolt in place, preventing rotation and ensuring a firm, secure fit.

Durability and Strength

Carriage bolts are commonly crafted from robust materials such as carbon steel and stainless steel, ensuring exceptional durability.

Aesthetic Appearance

The smooth head design minimizes damage to wood and metal surfaces, providing a clean finish.

Versatility

Suitable for both wood and metal applications, offering flexibility across various industries.

Conclusion

Carriage bolts are a crucial fastening solution in many industries due to their secure hold, durability, and versatility. With various types, standards, and key manufacturers offering high-quality options, carriage bolts continue to play a vital role in construction, automotive, and furniture manufacturing.
