Button Head Socket Cap Screws-Stainless Steel 18-8 (304)-Allen Hex Button Head Screws

description

1.Reliable Performance – Crafted from 18-8 (A2/304) stainless steel, these button-head socket cap screws combine ≈ 70 ksi / 480 MPa tensile strength with excellent resistance to rain-water, mild chemicals, food acids, and salt-spray. The wide-diameter, low-profile button head spreads bearing load, while the deep hex-socket drive tolerates high torque without cam-out, making them ideal for both static and vibrating joints.

2.Broad Application Range – Favoured in machine enclosures, robotics, furniture, bicycle and motorcycle accessories, electronics housings, marine hardware, and architectural fittings where a smooth, snag-free head and enduring corrosion protection are required. Suitable for indoor or outdoor service from −196 °C to +425 °C.

3.Easy to Use – The internal hex recess accepts common Allen/hex keys for quick, one-handed installation in tight spaces; its rounded head reduces risk of injury or fabric snagging. Rolled UNC or metric threads engage smoothly and are less prone to galling thanks to a passivated, low-friction surface finish.

4.Assured Quality – Manufactured under ISO 9001 systems and compliant with ASME B18.3 / ISO 7380-2 dimensions and ISO 3506-1 mechanical requirements. Each lot is thread-gauge verified, hardness and tensile tested, magnetic-particle inspected, and passivated for maximum corrosion resistance; full EN 10204 3.1 material certificates and heat-lot traceability are supplied on request, ensuring dependable, long-service performance.
