| High Light | Carbon Steel Dacromet Hexagon Screw ，Hot Dip Galvanized Torx Screw ，10.9 12.9 Metal Pan Head Screw | ||
Carbon Steel 10.9 12.9 Dacromet Gumet Hot Dip Galvanized Hdg Hexagon Torx Cross Recess Pan Head Metal Screw
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.
| Industry | Usage |
|---|---|
| Automotive | High-strength applications in engines, heavy-duty machinery, and bridge construction |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions in various industries |
| Energy | Connecting power generation equipment and transmission lines |
| Architectural | Building structures, shipbuilding, and petrochemical equipment |
Wind turbine tower flanges – Grade 12.9 with Dacromet, withstands cyclic high loads.
Bridge seismic stoppers – HDG for long-term outdoor protection.
Heavy mining machinery – Grade 10.9 with Geomet, resists mud and water.
Port crane rail clips – HDG resists seawater.
Petrochemical reactor manways – Dacromet coating resists chemical atmospheres.
Ultra-high strength – 10.9/12.9 for extreme load requirements.
Premium anti-corrosion coatings – Dacromet/Geomet, hydrogen embrittlement-free with excellent salt spray resistance; HDG for heavy-duty outdoor use.
Three drive options – suits various torque and tool requirements.
Pan head large bearing – suitable for thin or soft materials in high-strength connections.
No hydrogen embrittlement risk – Dacromet/Geomet processes are hydrogen-free.
