This hex cap screw is a Grade 8 fastener, manufactured from heat-treated alloy steel. Its zinc plating provides moderate corrosion resistance. Grade 8 hex cap screws are specified for applications requiring high tensile strength and proof load, offering a significant upgrade in strength compared to standard Grade 5 or unrated carbon steel fasteners, suitable for demanding structural and mechanical assemblies.
Used in heavy equipment, automotive suspension systems, and industrial machinery where bolt failure would compromise safety or function. The zinc finish delays surface rust formation, extending service life in outdoor or damp conditions, though it is not suitable for marine or highly corrosive environments.
