1/2-13 x 8 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. This size keeps the specified 1/2-13 thread and 8 1/2 in. length visible for matching drawings and maintenance records. Common uses include fixture design, maintenance repair, and production lines, where internal hex installation helps keep the joint accessible. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 1/2-13 Length: 8 1/2 in.
