Q: What materials and grades are available for your Precision Forged Square Head Bolt?
A: We usually use low-carbon to medium-carbon steel to produce flat Precision Forged Square Head Bolt products, and typically use grades 2 or 5. To provide higher strength and corrosion resistance, we offer flat head bolts made of ASTM A307 material or stainless steel (SS304/316). Material selection needs to be determined based on the tensile strength requirements of the application scenario and the specific environmental exposure conditions. We can provide you with the best advice based on your needs.
