Carbon steel coach bolts, also known as round head square neck bolts, are a common fastener mainly used for the connection of wood, metal and composite materials. They have high strength and good fastening effect. They are characterized by full or partial thread on the screw part, round head and square neck to help prevent rotation.
Wood structure connection:
Provide a stable connection in wooden frames, fences, and floor installations.
Metal and wood combination:
Used for fixing metal frames to wooden boards, widely used in construction and furniture manufacturing.
Outdoor engineering:
Due to its high strength and rust resistance, it is suitable for outdoor scenes such as bridges and scaffolding.
Vehicle manufacturing:
Common in parts that require high-strength connections such as trucks, trailers, and agricultural machinery.
High strength: Carbon steel can withstand large tensile and shear forces.
Economical: Compared with stainless steel, carbon steel is cheaper and more cost-effective.
Wide range of applications: It can be used for a variety of structural types, especially the connection between wood and metal.
Easy processing: The material is easy to manufacture, cut and process, suitable for large-scale production.

1.In machinery manufacturing, what are the advantages of blackened carbon steel carriage bolts over other bolts?
In machinery manufacturing, its cost is relatively low, and it is a good choice for some non-critical parts that do not require particularly high appearance and are not extremely strict in load requirements. For example, in the fixing of the outer shell of some agricultural machinery or the connection of internal non-critical brackets, blackened carbon steel carriage bolts can provide sufficient tightening force, and the black appearance can also cover up slight oil and dust to a certain extent, and its blackened surface has a certain wear resistance, which can resist slight friction during the operation of the machine.
2.When installing blackened carbon steel carriage bolts, how should the tightening torque be determined?
The tightening torque should be determined according to the specifications of the bolts (diameter, strength grade) and the properties of the connected materials. Generally speaking, you can refer to the relevant mechanical design manual or the technical parameters provided by the bolt manufacturer. If the tightening torque is too small, the connection is not firm and it is easy to loosen; if the tightening torque is too large, it may cause the bolt to be overloaded or even broken, or cause the connected material to deform and damage.
3.How to maintain the blackened carbon steel carriage bolts in use?
Regularly check whether the bolts have signs of looseness and rust. If looseness is found, re-tighten them according to the specified tightening torque. For rust, if the rust is light, you can first sand it off with sandpaper and then apply anti-rust oil; if the rust is heavy, you may need to replace the bolts. In harsh environments, the inspection cycle can be appropriately shortened, and some protective measures can be taken at the beginning of bolt installation, such as painting the surface or wrapping it with anti-rust materials.
