Flanged Button Socket Head Cap Screw-304 Stainless Steel-Full Thread-ISO7380-2

描述

1.Superior Performance – Cold-formed from 18-8 (A2 / 304) stainless steel and work-hardened to ≈ 80 ksi / 550 MPa tensile strength, these flanged button socket head cap screws unite a broad, built-in washer with a low-profile domed head. The integral flange spreads clamp load, resists pull-through in thin sheet and soft plastics, and dampens vibration; meanwhile the alloy’s chromium-rich passive film shields against rain-water, salt-spray, food acids, and most industrial chemicals over a service window of −196 °C to +425 °C.

2.Wide Application Range – Ideal for machinery guards, robotics panels, automotive trim, appliance housings, bicycle accessories, marine hardware, and architectural fixtures where a smooth, snag-free head must sit above the surface yet still distribute load without adding separate washers. Frequently used in aluminium extrusions, composite panels, and thin stainless sheet for both indoor and outdoor service.

3.Installation Made Easy – The deep internal hex accepts standard Allen keys or power bits for quick, one-handed tightening in confined spaces. An integrated flange eliminates loose washers, cuts assembly time, and prevents surface marring. Rolled UNC or metric threads start easily and run smoothly, while chamfered tips guide straight into pre-tapped holes, reducing cross-threading and galling.

4.Proven Quality – Produced under ISO 9001 systems and compliant with ASME B18.3 / ISO 7380-2 dimensional standards plus ISO 3506-1 mechanical requirements. Each lot is thread-gauge verified, hardness and tensile tested, magnetic-particle inspected, and passivated for maximum corrosion resistance. EN 10204 3.1 material certificates and laser-etched heat-lot codes provide full traceability, ensuring dependable, long-service performance in demanding environments.
