DIN 912 is a widely used hexagon socket head screw standard in industrial applications. Commonly referred to as an Imbus bolt, it features a cylindrical head with an internal hex socket, allowing for high torque fastening using an Allen key or hex wrench. These screws are made of high-strength steel, ensuring secure and durable connections in machinery, automotive, construction, and aerospace industries.
DIN 912 screws comply with ISO 4762, ensuring standardized dimensions, material quality, and tolerances across manufacturers, making them fully interchangeable between different brands.
Key Features
✅ Hexagon Socket Head Design
- Allows for high torque application without damaging the bolt.
- Ideal for tight spaces where external wrenches cannot be used.
✅ High-Tensile Strength
- Made from hardened alloy steel (8.8, 10.9, 12.9 grades) for heavy-duty applications.
- Provides superior load-bearing capacity and durability.
✅ Precision Engineering
- Manufactured with tight tolerances, ensuring a perfect fit in machinery and structural components.
✅ Material and Surface Coating Options
- Carbon Steel (8.8, 10.9, 12.9) – For high-strength applications.
- Stainless Steel (A2, A4) – Offers corrosion resistance in marine and outdoor environments.
- Surface Treatments Available: Zinc-plated, black oxide, hot-dip galvanized, and phosphate coatings for enhanced durability and rust prevention.
✅ Industry Applications
- Machinery & Robotics – Used for precision fastening in automated systems.
- Automotive & Aerospace – Ensures secure connections in high-vibration environments.
- Construction & Infrastructure – Ideal for structural fastening and load-bearing applications.
- Renewable Energy & Heavy Equipment – Used in wind turbines, industrial machinery, and steel structures.
