Product Description

Carbon Steel 10.9 12.9 Dacromet Gumet Hot Dip Galvanized Hdg Hexagon Torx Cross Recess Pan Head Metal Screw

Product Description

This pan head screw is manufactured from high-strength carbon steel with property classes 10.9 or 12.9 – among the highest strength grades available. Finishes include three high-performance options: Dacromet, Geomet, and Hot Dip Galvanized (HDG) . Dacromet and Geomet are chromium-free zinc-aluminium coatings with excellent salt spray resistance (500-1000 hours) and no hydrogen embrittlement risk – critical for high-strength fasteners. HDG provides a thick zinc layer (40-70μm) for outdoor steel structures. Drives: hexagon head, Torx, and cross recess – for varying torque requirements. The pan head offers a large bearing surface. This combination of high strength and superior corrosion protection is ideal for wind power, bridges, and heavy machinery critical connections.
