1/4-20 x 3/8 316 Stainless Steel Flat Head Socket Cap Screw is designed for finished assemblies where a smooth surface reduces catching points and improves service access. The design helps solve the common problem of securing a cover without leaving hardware proud of the surface. Its chloride resistance is valuable for marine hardware, pump covers, valve covers, and exposed equipment panels. A hex socket allows the screw to be tightened through the head while preserving the smooth countersunk form. Typical applications include marine hardware, outdoor cabinets, pharmaceutical equipment, and finished machinery surfaces. Industrial distributors can stock this size for customers replacing flush stainless fasteners in corrosive environments.
