1/4-20 x 2 1/2 18-8 Stainless Steel Flat Head Socket Cap Screw supports assemblies that need top-side socket drive access, 82-degree flat-head geometry, and reduced snag points after installation.
Common uses include packaging machinery, instrument housings, and service panels, where a clean exposed face supports maintenance access without raised hardware. The flat head form helps designers avoid raised fastener edges on panels, covers, and moving-equipment areas when the countersink is prepared correctly. The 18-8 stainless steel material is selected for general corrosion resistance, clean appearance, and ordinary moisture exposure in indoor industrial environments and general-purpose outdoor equipment.
For this 1/4-20 thread and 2 1/2 in. length, the dimensional data helps engineers confirm body diameter, head clearance, countersink fit, and socket tooling before release to purchasing or maintenance. Cold Headers gives distributors, maintenance teams, and sourcing departments a clear way to specify the exact stainless flat head socket screw required.
