1/4-20 x 1 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. This geometry is different from button head or standard socket head styles because the head is designed to nest into a matching countersink. 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 1 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.
