Socket Head Cap Screws

Socket head cap screws, commonly known as Allen Key bolts, represent a distinct category of screws engineered with a hexagonal (hex) internal drive embedded within the head. This unique design distinguishes them from conventional screws, as they are specifically crafted for tightening and loosening using an Allen wrench or hex key, as opposed to traditional screwdrivers. This hexagonal drive style sets socket screws apart from other popular screw head types such as Phillips head, slotted, flathead screws, and Pozidriv screws.
