4-40 x 1 1/4 316 Stainless Steel Flat Head Socket Cap Screw is an excellent choice for recessed hardware locations where engineers need 316 stainless steel and socket-drive installation. A flush head helps prevent interference with adjacent components, sliding parts, protective guards, or operator contact points. 316 stainless steel is often chosen where corrosion resistance is needed around pump assemblies, valve assemblies, and marine hardware. A recessed hex socket supports assembly and service access where tool clearance around the head is limited. Typical applications include marine hardware, outdoor cabinets, pharmaceutical equipment, and finished machinery surfaces. Plant maintenance teams can source this size for recurring cover, enclosure, and washdown equipment repairs.
