1/4-20 x 2 1/4 316 Stainless Steel Flat Head Socket Cap Screw supports designs where fastening hardware must remain accessible while keeping the outside surface smooth. Recessed installation helps protect the fastener head while keeping the assembly easier to wipe down or inspect. Its stainless construction is useful for chemical processing, pharmaceutical equipment, and outdoor applications where moisture is present. A recessed hex socket supports assembly and service access where tool clearance around the head is limited. The fastener is appropriate for OEM machinery, architectural hardware, coastal installations, and outdoor equipment. Industrial distributors can stock this size for customers replacing flush stainless fasteners in corrosive environments.
