12-28 x 1/2 Alloy Steel Socket Head Cap Screw supports industrial fastening where the socket head, internal hex drive, and verified head dimensions help match existing designs. The exact 12-28 x 1/2 size helps buyers align the fastener with replacement sourcing without changing the specified size. The screw is useful across processing equipment, automation systems, and assembly equipment 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: 12-28 Length: 1/2 in. Nominal Body Diameter: .215 in.
