Carbon Steel Black Flat Head Square Neck Galvanized Short Carriage Bolt
Product Description
The short blackened carbon steel carriage bolt is a short carriage bolt made mainly of carbon steel with a blackened surface. Its short design makes it suitable for installation scenarios with limited space, such as some small devices or compact component connections. The carbon steel material gives it good mechanical properties, such as high strength and toughness, and can withstand certain tensile and shear forces. The blackening treatment forms a black oxide film on its surface, which improves the wear resistance and rust resistance of the bolt to a certain extent, and also gives the bolt a rustic appearance.
Product Details
Production Process
Product Application
Due to its short design, its length is usually determined according to the specific application requirements, which may range from a few millimeters to more than ten millimeters. It is widely used in the assembly of small machinery, electronic product housings, or the fixing of precision instruments that require precise control of the bolt length. For example, in the fixing of the housing of a small motor, the short bolt can effectively fix the housing together without affecting the internal structural space of the motor. When the circuit board of some electronic products is fixed to the housing, the short blackened carbon steel carriage bolt can also play a good role because its length will not interfere with the layout of other components on the circuit board.
Product Feature
Compared with stainless steel carriage bolts, short blackened carbon steel carriage bolts are cheaper and more economically advantageous in some projects that do not require high anti-rust properties and have limited budgets. Compared with ordinary carbon steel bolts (non-blackened), its surface blackening treatment improves its wear resistance and rust resistance, making it more suitable for use in environments with slight friction or slightly high humidity. For example, in the connection of some small indoor wood products, blackening can reduce the damage to the bolt surface caused by wood friction, and to a certain extent resist the risk of rust caused by changes in indoor humidity.

FAQ
1.What are the main carbon steel components in blackened carbon steel carriage bolts? What effect do these components have on the performance of the bolts?
Carbon steel is mainly composed of iron and carbon, and may also contain a small amount of silicon, manganese, sulfur, phosphorus and other elements. The carbon content affects the hardness and strength of the bolt. The higher the carbon content, the greater the hardness and strength, but the toughness will decrease. Manganese can improve the strength and toughness of steel, and silicon can increase the strength and hardness of steel. Sulfur and phosphorus are generally harmful impurities. Excessive content can cause hot brittleness and cold brittleness of steel.
2.Will the strength and toughness of carbon steel carriage bolts change after blackening?
Blackening is mainly a surface treatment method. Under normal circumstances, it has little effect on the strength and toughness of the bolts. Because blackening forms an oxide film on the surface of the bolt, it does not change the internal structure of the carbon steel, so it will not change its own mechanical properties such as strength and toughness.
3.What are the blackening processes for blackened carbon steel carriage bolts? Which process is more commonly used?
The blackening processes mainly include alkaline oxidation method and room temperature blackening method. The alkaline oxidation method is to form an oxide film on the metal surface in a high-temperature alkaline solution. Its film quality is good, and its wear resistance and corrosion resistance are relatively strong. The room temperature blackening method is to form an oxide film through chemical agent reaction at room temperature. The operation is relatively simple and the cost is low. In actual production, the alkaline oxidation method is more commonly used because it can produce a black oxide film with more stable quality and better performance.
