1 1/2-6 x 8 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. The size callout supports stockroom identification and purchasing review when actuated equipment cannot accept a substitute fastener. It is frequently used in manufacturing plants, robotics, and maintenance repair when socket engagement is preferred over external-wrench access. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1 1/2-6 Length: 8 in.
