The hex head style can be fastened with a wrench or socket driver, enabling high strength tightening and reliable connections. They can often be fastened with or without a hex nut. Hex head cap screws are used for projects across virtually all industries, grade 8 bolts are most often called for in those projects that demand a high tensile strength, resistance to wear, and high reliability under extreme conditions. A grade 8 hex cap screw can be identified as having six lines on the head; sometimes the bolt might also include a manufacture imprint too.
