1/4-20 x 1/2 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.
For many plant, automation, and packaging environments, 18-8 stainless steel offers a practical balance of corrosion resistance and broad industrial usability.
Cold Headers has supplied specialty socket fasteners since 1962, helping purchasing teams source exact sizes for industrial maintenance and production work.
The low head geometry gives this 1/4-20 x 1/2 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.
