1/4-28 x 1/2 18-8 Stainless Steel Low Head Socket Cap Screw helps solve clearance problems in machine assemblies where a conventional socket head projects too far above the surface.

For many plant, automation, and packaging environments, 18-8 stainless steel offers a practical balance of corrosion resistance and broad industrial usability.

For engineering departments and industrial buyers, Cold Headers helps identify low head socket screw sizes that fit specific clearance and assembly requirements.

The low head geometry gives this 1/4-28 x 1/2 fastener a reduced profile for compact equipment housings and panel assemblies, where internal wrenching keeps the drive feature inside the head when external wrench clearance is limited. It may also be specified for electrical enclosures and control panels, where the low head design helps keep hardware projection controlled on exposed or space-limited surfaces.

Use the verified dimensions below to compare nominal body diameter, head diameter, head height, hex socket size, and key engagement against the available space in the assembly.
