Detail description

Carriage Bolt Black Oxide 3
Carriage Bolt Zinc Plate 8

Carriage bolt refers to the round head and square neck screw.

Generally speaking, a bolt is used to connect two objects, usually through a light hole, and needs to be used in conjunction with a nut, not a single connection. Tools usually use a wrench. The head is mostly hexagonal, generally large. The carriage bolt is applied in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating. The carriage bolt can move parallel in the groove. Because the head of the carriage bolt is round, there is no cross slot or hex and other available tools design, in the actual connection process can also play the role of anti-theft.

Materials: carbon steel, Q235, 45# steel, stainless steel
Nominal diameter: 5mm–20mm
Length: 15 mm – 300 mm
Surface treatment method: zinc plating, chrome plating, copper plating, black oxide
