What Are The Standard of Carriage Bolts?
Carriage bolts are manufactured to specific standards that define their dimensions, materials, strength, and other characteristics. These standards ensure that bolts are consistent and compatible with other components in various applications.
As a professional fastener manufacturer, Xinchi is happy to share some of the primary standards that apply to carriage bolts.
- ASTM Standards
ASTM A307: Covers carbon steel bolts and studs ranging from 1/4 inch through 4 inches in diameter. This specification is commonly used for carriage bolts and includes Grade A (general applications) and Grade B (flanged joints).
ASTM F593: Specifies stainless steel bolts, hex cap screws, and studs, including those used for carriage bolts. It covers several grades depending on the type of stainless steel and its intended use.
- SAE Standards
SAE J429: This covers the mechanical and material requirements for externally threaded fasteners such as bolts. This includes Grade 1, 2, 5, and 8 carriage bolts, with varying levels of strength and material properties.
- ISO Standards
ISO 8677: Specifies the characteristics of carriage bolts with metric dimensions. This standard includes information on sizes, dimensions, and material properties.
- DIN Standards (German)
DIN 603: This is a specific standard for carriage bolts and square neck bolts. It outlines the size, material, and mechanical properties of these types of bolts, which are very similar to ISO standards but primarily used in European countries.
- BS Standards (British)
BS 4933: Specifies dimensions and properties for inch series carriage bolts, although this standard might be less commonly used today due to the prevalence of metric standards in international contexts.
