304-A2 Stainless Steel Phillips Round Head Machine Screw

304-A2 stainless steel Phillips round head machine screw is a TECTUL reference for assemblies with a nut or internal thread where the head remains visible and better corrosion resistance than zinc-plated steel is required. The actual lot reports stainless steel material, sale by unit, and inch thread family; the technical file separates it by round head, Phillips drive, inch thread, and 304-A2 stainless material. To buy without errors, validate head style, drive, diameter or pitch, usable length, and finish against the sample, drawing, or existing nut. ASME B18.6.3 is used as a public reference for machine screws in inch sizes; metric items are validated against ISO or DIN when the drawing requires it. We do not publish a single torque or capacity because the result depends on base material, thickness, lubrication, coating, head bearing, vibration, grip length, and tightening method.

Installation recommendations

• Start threading by hand to confirm that the pitch matches; if it binds, do not force installation.
• Confirm the complete size before installation; a visually similar thread can damage the nut or part.
• Use a bit, socket, or screwdriver in good condition to avoid stripping the head or marking the finish.
• Do not substitute zinc-plated steel, stainless steel, or brass/bronze without validating environment, corrosion, and assembly compatibility.
• Tighten in a controlled way so the head seats without deforming the part or damaging the internal thread.
