M2-A Through bolt offered by our company is a type of cap screw with a cylindrical head and hexagonal drive hole. This bolt has less tensile and yield strength than alloy sockets, but superior corrosion resistance. This bolt is very effective as well as economical to use. Our M2-A Through bolt is commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or socket. This bolt also retains mechanical and performance capabilities at higher than ambient temperatures.
