Hexagon Carbon Steel Bolts
Hexagon carbon steel bolts , as the most widely used fasteners in the industrial field, have the advantages of high strength, low cost and excellent processability.
- Material: Carbon steel
- Surface treatment: Zinc-plating
- Dimensions: Custom manufactured per specific requirements
Superior Characteristics of Hexagon Carbon Steel Bolts
1. Excellent mechanical properties
- Wide strength coverage: can be up to 4.8 to 12.9 grades through heat treatment (tensile strength 400-1200MPa).
- High toughness: especially suitable for impact load scenarios (e.g. vibrating parts of heavy equipment).
2. Strong processing adaptability
- Cold heading/hot forging molding, suitable for large-scale automated production.
- Easy to carry out secondary processing such as turning and rolling.
3. Cost-effectiveness
- The price of raw materials is only 1/3 of stainless steel, 1/20 of titanium alloy.
- The mass production cost is more than 40% lower than alloy steel.

Applications of Hexagon Carbon Steel Bolts
Key application scenarios by strength level
1. Medium and low strength (4.8-8.8)
- Building Structure: embedded bolts, color steel plate fixation (cost sensitive scenario)
- Furniture Assembly: universal bolts to connect metal frames
- Agricultural Machinery: harvester shell, grain bin bracket (with anti-rust treatment)
2. High strength (10.9-12.9)
Automobile Manufacturing:
- Engine cylinder block bolts (12.9 grade, torque accuracy requirement ±5%)
- Key components of the chassis suspension (fatigue strength> 10^7 cycles)
Wind Power Equipment:
- Tower flange connection (grade 10.9, M36 or above, pre-tightening force over 400kN)
Bridges:
- Rail brake bolt (anti-vibration and loosening design)
