3-48 x 3/4 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. With a 3-48 thread and 3/4 in. length, it fits machine frames and brackets where size interchangeability matters. The screw is useful across manufacturing plants, industrial automation, and maintenance repair when a compact internal-hex fastener is required. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 3-48 Length: 3/4 in.
