M18 M22 Hdg Hot Dig Galvanized Dacromet Geomet Hex Socket Head Machine Metal Screw Din912 Grade 4.8 8.8 10.9 12.9
These large-diameter hex socket head cap screws are available in M18 and M22, designed for heavy-duty and highly corrosive environments. Material: carbon or alloy steel with property classes 4.8, 8.8, 10.9, or 12.9. Surface finishes include three high-performance options: Hot Dip Galvanized (HDG), Dacromet, and Geomet. HDG provides a thick zinc layer (40-70μm) for outdoor steel structures; Dacromet and Geomet are chromium-free zinc-aluminium coatings offering excellent salt spray resistance (up to 1000 hours) with no hydrogen embrittlement risk. Head conforms to DIN912, allowing high torque via large hex keys.
| 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 flange connections – Grade 12.9 + Dacromet for cyclic loads.
Bridge seismic stoppers – HDG provides 30+ years rust protection.
Chemical reactor manways – Geomet coating resists acid mist.
Mining machinery chassis – M22 high-strength bolts.
Port crane rail clips – HDG resists seawater.
Large diameters, high load capacity – M18/M22 for heavy connections.
Multiple strength grades – from 4.8 to 12.9 for design flexibility.
Premium anti-corrosion coatings – HDG, Dacromet, Geomet for various aggressivity levels.
No hydrogen embrittlement – Dacromet/Geomet safe for high-strength bolts.
DIN912 standard – hex drive allows very high torque transmission.
