1/4-20 x 6 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 1/4-20 thread and 6 1/2 in. length, it fits machine frames and brackets where size interchangeability matters. The screw is useful across processing equipment, packaging machinery, and material handling when a compact internal-hex fastener is required. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. This keeps the listing focused on the fastener geometry rather than broad catalog language. Technical Highlights Material: Alloy Steel Thread: 1/4-20 Length: 6 1/2 in. Nominal Body Diameter: .250 in.
