1 1/4-7 x 5 1/2 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. With a 1 1/4-7 thread and 5 1/2 in. length, it fits drive components where size interchangeability matters. Common uses include maintenance shops, tooling, and assembly equipment, where internal hex installation helps keep the joint accessible. Internal hex drive access helps installation in compact assemblies, guards, housings, and fixture plates. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1 1/4-7 Length: 5 1/2 in.
