5/8-18 x 2 1/4 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. The exact 5/8-18 x 2 1/4 size helps buyers align the fastener with service work where the exact thread and length are already defined. The screw is useful across maintenance repair, material handling, and packaging machinery when a compact internal-hex fastener is required. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 5/8-18 Length: 2 1/4 in.
