(bs flange head bolts)
BS flange head bolts, engineered to British Standard specifications, deliver exceptional load distribution in high-pressure environments. Carbon steel variants account for 62% of global flange bolt consumption, driven by their 850 MPa tensile strength and corrosion-resistant coatings. Leading carbon steel flange head bolts manufacturers now utilize automated cold forging processes, achieving ±0.02mm dimensional accuracy across mass production batches.
Advanced manufacturing techniques enable carbon steel flange bolts to withstand temperatures from -50°C to 300°C. Proprietary surface treatments like zinc-nickel electroplating enhance durability, providing over 1,200 hours of salt spray resistance. Compared to standard hex bolts, the flange design reduces bearing surface pressure by 40%, preventing joint loosening in vibrating machinery.
