1/4-28 x 3/8 316 Stainless Steel Flat Head Socket Cap Screw is well suited for assemblies where a countersunk hole allows the fastener head to sit level with the surrounding part. A flush head helps prevent interference with adjacent components, sliding parts, protective guards, or operator contact points. 316 stainless steel supports demanding service around salt spray, cleaning fluids, and many industrial washdown environments. The internal drive supports controlled torque application in panels, housings, and cover plates. Common uses include equipment panels, machine covers, inspection covers, and electrical enclosures. Repair technicians can use the defined size when replacing countersunk hardware on panels or covers. It also supports standardization across related covers, guards, and enclosure assemblies.
