American carriage bolt, as defined by ANSI standards, are a type of fastener commonly used in various industries. The ANSI 18.5 standard specifies the dimensions and requirements for round head square neck carriage bolts. These bolts are characterized by their round head and a square neck under the head, which prevents the bolt from rotating when a nut is tightened.
Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.
Grade: The product grade different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.
Advantage:
Prevention of Rotation: The carriage bolt square neck design prevents the bolt from turning when a nut is tightened, ensuring a secure fit.
Versatility: They are suitable for a wide range of applications, including construction, automotive, and machinery.
Easy Installation: The round head allows for easy installation with a socket or wrench.
Corrosion Resistance: Often made from stainless steel (304/316), these bolts offer excellent resistance to corrosion, making them suitable for outdoor use.
Load Distribution: The square neck design helps distribute the load evenly, reducing the risk of damage to the connected parts.
Scope of
Application
Construction: Carriage bolt can be used in building structures where a secure connection is required.
Automotive Industry: Employed in the assembly of vehicles where a flush finish and secure fastening are needed.
Machinery and Equipment: Used in machinery frames and equipment where a secure and adjustable connection is needed.
Solar Mounting Systems: Utilized in solar panel mounting systems for securing panels to racks or structures.
Furniture and Display Systems: Ideal for use in systems that require frequent assembly and disassembly.
Quality
