The carriage bolt is also known as a round head square neck bolt. Its structure is quite unique, mainly consisting of the head, neck, and rod parts. The head is round and smooth, which prevents scratching the surface of the object being fixed during installation. The neck is square, which is a significant feature of the carriage bolt; the square neck can be embedded into the pre-drilled square hole of the object being fixed during installation, preventing the bolt from rotating. The rod part has threads for fitting with nuts to fasten objects together. Carriage bolts are usually made of materials such as carbon steel or stainless steel to ensure they have certain strength and corrosion resistance.
Specifications and Standards
The specifications of carriage bolts are mainly represented by diameter, length, etc. The diameter specifications generally include M6, M8, M10, etc. (M represents the nominal diameter of metric threads), while the length varies according to specific usage needs, ranging from a few centimeters to several tens of centimeters. Internationally, the production and use of carriage bolts follow relevant standards, such as ISO standards (International Organization for Standardization standards) and national standards of various countries. These standards specify requirements for the dimensional accuracy, mechanical performance, and material quality of carriage bolts to ensure they can work reliably in different application scenarios.
