1/4-20 x 3/8 Alloy Steel Socket Head Cap Screw is suited to assemblies that need an alloy steel cap screw for clamp load, service access, and compact installation. For fixture clamps, the 1/4-20 thread and 3/8 in. length help confirm the correct socket cap screw before installation. Applications often include robotics, assembly equipment, and production lines, especially where counterbored or close-clearance mounting is required. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/4-20 Length: 3/8 in.
