1/2-13 x 1 1/4 18-8 Stainless Steel Low Head Socket Cap Screw is selected when a stainless socket fastener must fit where a taller head would interfere with nearby machine components.

The material provides everyday corrosion resistance for production equipment, commercial hardware, and maintenance work without overstating the application.

The low head geometry gives this 1/2-13 x 1 1/4 fastener a reduced profile for machine guards and access panels, where the reduced head profile helps prevent interference around removable covers and moving components. It may also be specified for inspection fixtures and tooling plates, where a reduced head height can help maintain clearance around clamps, slides, locating features, and tooling details.

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.

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