Overview

Long blackened carbon steel coach bolt is a long coach bolt made of carbon steel as the base material and treated with blackening. Its length advantage enables it to pass through thicker materials for fastening, and is suitable for connecting thick plates, large brackets and other structures. The carbon steel material ensures that it has good strength and toughness, and can withstand large tensile and shear forces. The blackened surface not only has certain rust and wear resistance, but also presents a black appearance, which can add a simple style to some occasions where appearance is required.

Application of Black Coach Bolt

• The long length range is wide, which may range from tens of millimeters to hundreds of millimeters, depending on the actual application.
• In the field of construction: When used to fix solar panel brackets to roof structures, if the roof structure is thick or bolts need to penetrate multiple layers of materials for fixing, long bolts can play a role.
• In large-scale machinery manufacturing: Such as fixing the frame of heavy equipment, its longer size can ensure the stability of the connection, and can pass through thicker metal parts to connect the parts tightly together.

Feature of Black Coach Bolt

• Compared with aluminum alloy bolts: Long blackened carbon steel coach bolts are stronger and more suitable for occasions with larger loads.
• Compared with galvanized bolts: Black treatment has slightly weaker anti-rust ability, but in some environments where anti-rust requirements are not particularly high, long black carbon steel coach bolts are less expensive.
• Aesthetic advantage: And in some buildings or equipment of a specific style, the black appearance may be more in line with the overall design style.
