Buy Carriage Bolt

A carriage bolt, also known as a coach bolt, is a fastener with a domed or countersunk head, and the shank is topped by a short square section under the head. This design allows it to self-lock into wood or other soft materials, preventing rotation during tightening. This guide explores the different types, sizes, materials, and applications of carriage bolts, helping you make informed purchasing decisions for your projects. You can buy carriage bolts from various sources, including online retailers and local hardware stores. Understanding the specifications and features of different carriage bolts is crucial for selecting the right fastener for your needs. Whether you're working on woodworking projects, construction, or any other application requiring secure fastening, this guide will provide the necessary information.Understanding Carriage BoltsCarriage bolts, also known as coach bolts, are specialized fasteners designed for use in wood and other soft materials. Their distinguishing feature is a domed or countersunk head and a square shoulder just below the head. This square shoulder is designed to grip the material being fastened, preventing the bolt from turning when the nut is tightened.Key Features of Carriage Bolts Domed Head: Provides a clean, finished look and prevents tampering. Square Shoulder: Grips the material and prevents rotation. Variety of Materials: Available in steel, stainless steel, and other materials to suit different environments. Various Sizes: Offered in a wide range of diameters and lengths to accommodate different applications.Types of Carriage BoltsDifferent types of carriage bolts are available to meet specific needs. Understanding these variations can help you choose the best bolt for your project.

They are often used in applications where vibration or movement is a concern.Countersunk Carriage BoltsThese bolts have a countersunk head that sits flush with the surface of the material being fastened. They are ideal for applications where a low-profile head is desired.Elevator BoltsWhile technically a type of carriage bolt, elevator bolts have a large, flat head and a shallow countersunk design. They are commonly used in conveyor systems and other applications where a smooth surface is required.Materials and FinishesThe material and finish of a carriage bolt play a crucial role in its durability and suitability for different environments.SteelSteel carriage bolts are the most common and cost-effective option. They are suitable for general-purpose applications, but may be susceptible to corrosion in harsh environments.Stainless SteelStainless steel carriage bolts offer excellent corrosion resistance, making them ideal for outdoor applications, marine environments, and food processing equipment. Types 304 and 316 are commonly used.Galvanized SteelGalvanized steel carriage bolts are coated with a layer of zinc to protect against corrosion. They are a good compromise between cost and corrosion resistance.Other MaterialsCarriage bolts can also be made from other materials like aluminum and brass, each offering unique properties for specific applications.Applications of Carriage BoltsCarriage bolts are versatile fasteners used in a wide range of applications. Their unique design makes them particularly well-suited for woodworking and construction projects. The square shoulder is designed to grip the material and prevent the bolt from turning when the nut is tightened, providing a secure and reliable fastening solution.WoodworkingCarriage bolts are commonly used in woodworking projects such as furniture construction, deck building, and fence installation. The domed head provides a clean, finished look, and the square shoulder prevents the bolt from spinning as the nut is tightened.ConstructionIn construction, carriage bolts are used to fasten timber framing, connect structural components, and secure various building materials. Their strength and durability make them a reliable choice for demanding applications.Marine ApplicationsStainless steel carriage bolts are often used in marine applications due to their excellent corrosion resistance. They are used to fasten boat components, docks, and other structures exposed to saltwater environments. It's important to choose the right type of stainless steel, such as 316, for the best performance.AutomotiveAlthough less common than other types of bolts in automotive applications, carriage bolts can be found in specific areas, such as securing seats or mounting accessories. Their flush head design can be advantageous in certain situations.How to Choose the Right Carriage BoltSelecting the correct carriage bolt for your project involves considering several factors, including size, material, and application. Here are some key considerations:Determine the Correct SizeMeasure the thickness of the materials you are fastening to determine the appropriate bolt length. The bolt should be long enough to pass through both materials and accommodate the nut and any washers. The diameter of the bolt should be appropriate for the load it will bear. Consult engineering tables for load ratings.Select the Appropriate MaterialChoose a material that is compatible with the environment in which the bolt will be used. Stainless steel is ideal for outdoor and marine applications, while steel may be suitable for indoor or protected environments. Consider the potential for corrosion and select a material or finish that will provide adequate protection.Consider the ApplicationDifferent applications may require specific types of carriage bolts. For example, ribbed neck carriage bolts may be preferred for applications where vibration is a concern. Countersunk carriage bolts may be used where a flush surface is desired.Check Specifications and StandardsEnsure that the carriage bolts you select meet relevant industry standards and specifications. This will help ensure that they are of high quality and suitable for their intended purpose.Where to Buy Carriage BoltsYou can buy carriage bolts from a variety of sources, including:Hardware StoresLocal hardware stores typically carry a selection of carriage bolts in various sizes and materials.
