3-48 x 7/8 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. With a 3-48 thread and 7/8 in. length, it fits machine frames and brackets where size interchangeability matters. The screw is useful across material handling, processing equipment, and maintenance shops when a compact internal-hex fastener is required. Socket engagement helps technicians apply installation torque from above the head in constrained layouts.
