Flat Round Head Hex Socket Head Screw-304 Stainless Steel -Hex Socket Drive Machine Screw-Bright Finish

描述

1.Reliable Performance – Made from 18-8 (A2/304) stainless steel, these flat-round head machine screws deliver ≈ 70 ksi / 480 MPa tensile strength and stand up to rain-water, salt-spray, food acids, and most industrial chemicals from −196 °C to +425 °C. The low-profile domed head with a broad, flat bearing underside distributes clamp load over a larger area than pan or hex heads, preventing pull-through in thin sheet metal and plastic housings while giving a clean, snag-free appearance.

2.Broad Application Range – Ideal for electronics enclosures, appliance cabinets, HVAC panels, lighting fixtures, marine hardware, architectural trim, furniture assembly, and general MRO where a smooth, decorative head and long-term corrosion protection are essential. Commonly paired with nyloc nuts or tapped holes in aluminum, steel, and composite materials for indoor or outdoor service.

3.Easy to Install – Supplied with deep Phillips, Pozidriv, or Torx recess options that center the driver bit and minimize cam-out, enabling quick one-handed installation even in tight corners. Chamfered tips start easily in pre-tapped holes, and precision-rolled UNC or metric threads turn smoothly with reduced risk of galling thanks to a passivated, low-friction surface.

4.Assured Quality – Produced under ISO 9001 systems and compliant with ASME B18.6.3 / ISO 7045 dimensional standards plus ISO 3506-1 mechanical requirements. Every batch is thread-gauge verified, hardness and tensile tested, passivated for maximum corrosion resistance, and laser-etched with heat-lot codes. EN 10204 3.1 material certificates provide full traceability, guaranteeing consistent, long-service performance in demanding environments.
