DIN939 Double Head End Stud Bolt are a type of fastener that complies with the German industrial standard DIN939-1995. They are characterized by having two threaded ends and are usually used to connect two components to enhance the stability and safety of the structure.
DIN939 stud bolts are usually made of carbon steel, alloy steel or stainless steel. These materials have good mechanical properties and corrosion resistance and are suitable for various environmental conditions. Grades usually include 4.8, 8.8, 10.9 and 12.9, which represent the tensile strength and yield strength of the bolts. For example, bolts of grade 4.8 have lower strength and are suitable for general applications; while bolts of grade 12.9 have extremely high strength and are suitable for applications that need to withstand extreme pressure or require a high safety factor.
