1. High-Performance-Konstruktion - Präzisionsbearbeitung aus arbeitsgehärtetem 18-8 (A2/304) Edelstahl, diese Flachkopf-Hexas-Kappenschrauben bieten eine Zugfestigkeit von ≈ 100 ksi / 690 MPa und widerstehen Regenwasser, Salzspray, Nahrungsmittelsäuren und den meisten Industriechemikalien zwischen -196 ° C und +425 ° C. Die 82° (metrisch 90°) Flache Kopfsitze bündig für eine glatte, hakenfreie Oberfläche, dennoch liefert robuste Klemmkraft ohne Kopf Verformung unter Vibration und bietet gute Festigkeit und Korrosionsbeständigkeit in schlechten Umgebungen.

2.Broad Application Range – this type can be widely used in the home and office appliance, communication equipments, ship assembly , the mechanical industry and small repairs around shops, garages or home furniture fasteners.Favoured in sheet-metal enclosures, CNC machinery, aerospace and automotive bodywork, marine hardware, electronics chassis, architectural façades, and premium furniture—any assembly that demands a flush profile combined with long-term corrosion protection. Ideal for tight clearances where traditional hex bolts or pan heads would protrude.

3.Easy to Operate – Deep internal hex recess accepts standard Allen keys or power bits for one-handed tightening in confined spaces, transmitting high torque without cam-out. The countersunk head self-centres in pre-formed 82°/90° chamfers for accurate alignment, while rolled UNC or metric threads start easily, run smoothly, and minimize galling; chamfered tips guide quickly into tapped holes.

4.Assured Quality – Produced under ISO 9001 systems and compliant with ASME B18.3 / ISO 10642 dimensions 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, guaranteeing consistent, long-service performance in demanding environments.
