With a 3/4-16 thread and 3 3/4 in. length, it fits counterbored mounting points where size interchangeability matters. Common uses include machine tools, robotics, and engineering departments, where internal hex installation helps keep the joint accessible. 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: 3/4-16 Length: 3 3/4 in.
