304 Stainless Steel Phillips Flat Head Sheet Metal Screw

304 stainless steel Phillips flat head sheet metal screw is a TECTUL reference for flush sheet metal fastening on covers, panels, and equipment exposed to moisture or washdown. The actual lot reports material 304 stainless steel, sale by unit and stainless steel, inch thread. It is distinguished by the countersunk flat head combined with 304 stainless steel; it is not the stainless pan head version. To select without errors, validate head style, drive, finish, commercial diameter, and length against the sample or drawing. ASME B18.6.3 is used as a public reference for machine screws and self-tapping screws in inch sizes; the commercial size of the lot is confirmed against a sample or drawing. We do not publish a single torque or capacity because the result depends on base material, thickness, hole preparation, lubrication, coating, head bearing, vibration, and tightening method.

Installation recommendations

• If the sheet metal is hard or thicker, validate whether a pilot hole is required.
• Confirm diameter and length before installation; a similar size can damage the thread or leave insufficient fastening.
• Use a bit, socket, or driver in good condition to avoid stripping the head or marking the finish.
• Do not substitute zinc-plated, black oxide, or stainless steel without validating moisture, washdown, or outdoor exposure.
• Tighten in a controlled way so the head seats without deforming the sheet metal.
