Product Description
Carriage Bolt
Carriage bolts, also known as round-head square-neck screws, are a type of fastener consisting of a hemispherical head and a threaded cylindrical shank. They are designed to be used in conjunction with nuts to securely connect two objects with through holes. Commonly used in industries such as construction, furniture, and machinery manufacturing, carriage bolts are renowned for their vibration resistance, anti-loosening properties, and high load-bearing capacity. These bolts are classified into large semi-round head (GB/T14 and DIN603) and small semi-round head (GB/T12-85) types based on head size. Common materials include carbon steel and stainless steel (SUS304, 316), with surface treatments such as galvanizing, chroming, and copper plating available.
