3-48 x 7/16 18-8 Stainless Steel Socket Head Cap Screw is specified when engineers need a stainless internal-hex fastener with everyday corrosion resistance and compact head geometry. The stainless construction supports service in many maintenance, assembly, agricultural, and light chemical exposure environments. The internal hex drive supports positive tool engagement where surrounding components limit wrench clearance. Typical placements include machine tools, fixture design, and engineering departments where general corrosion resistance and internal-hex access are useful. Design engineers can compare the listed head dimensions and hex key size against counterbore and tooling requirements. Technical Highlights: Material: 18-8 Stainless Steel; Thread: 3-48 UNC; Length: 7/16 in.; Nominal Body Diameter: 0.099 in.; Head Diameter: 0.161 in. max / 0.154 in. min; Head Height: 0.099 in. max / 0.095 in. min; Hex Key Size: 5/64; Drive Type: internal hex.
