5/16-18 x 2 18-8 Stainless Steel Low Head Socket Cap Screw gives engineers an 18-8 stainless low head socket cap screw for equipment designs with limited overhead clearance.

Compared with carbon steel fasteners, 18-8 stainless steel is often selected for cleaner appearance and resistance to normal atmospheric exposure.

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 5/16-18 x 2 fastener a reduced profile for inspection fixtures and tooling plates, where a reduced head height can help maintain clearance around clamps, slides, locating features, and tooling details. It may also be specified for MRO repair operations and production equipment, where the exact thread and length help maintenance teams match fasteners used in tight industrial assemblies.

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.
