A hex head bolt, named for its hexagonal-shaped head, is designed for use with a wrench or socket tool. The 8mm refers to the diameter of the bolt's shaft, which determines its load-bearing capacity. This size is commonly used in medium-duty applications where a balance between strength and ease of handling is necessary. The metric system, as opposed to imperial measurements, is employed here, reflecting the global acceptance and standardization of metric fasteners.
