12-24 x 3 1/2 Alloy Steel Socket Head Cap Screw supports industrial fastening where the socket head, internal hex drive, and verified head dimensions help match existing designs. For machine frames and brackets, the 12-24 thread and 3 1/2 in. length help confirm the correct socket cap screw before installation. Industrial buyers may specify it for manufacturing cells, maintenance repair, and machine tools where head geometry and drive access need to be predictable. 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: 12-24 Length: 3 1/2 in.
