Professional industrial-grade three-combination screws, precision-engineered to comply with DIN912 standards, designed for efficient mechanical assembly, equipment installation, and quick fastening applications. Crafted from premium 304 stainless steel, these pre-assembled combination screws integrate a hexagonal (hex) cup head screw, elastic washer (elastic pad), and additional components in one piece—eliminating the need for separate fasteners and streamlining your assembly process.
Our DIN912 three-combination screws feature a sleek cup head design paired with a precision hexagonal (hex) drive, ensuring a secure grip during installation and a tight, professional fit with mechanical components. Available in extra large and extra small sizes, they adapt to diverse assembly needs—from compact electronic equipment to heavy-duty industrial machinery. The pre-installed elastic washer provides excellent anti-loosening performance, preventing slippage under continuous mechanical vibration, while also offering shock absorption and pressure distribution to protect connected parts.
Constructed from 304 stainless steel, these combination screws deliver reliable corrosion resistance, rust proofing, and durability—ideal for indoor, outdoor, and light industrial environments. They resist moisture, mild chemicals, and daily wear, ensuring long-term performance without rust or deformation. The precision-machined threads (compliant with DIN912 standards) ensure universal compatibility with standard nuts, washers, and mechanical components, making them a versatile choice for various projects.
Designed for efficiency and convenience, these pre-assembled three-combination screws save time on assembly by eliminating the need to handle separate screws and washers. The hexagonal drive allows for easy torque application with standard hex keys (Allen keys), preventing slipping or stripping during installation. Whether used in industrial machinery, electronic enclosures, furniture hardware, automotive components, or precision instruments, these screws meet strict quality standards, ensuring consistent performance and reducing maintenance downtime.
The extra large and extra small size options cater to specialized assembly needs—perfect for projects where standard-sized combination screws are too big or too small. Their all-in-one design makes them a go-to choice for engineers, maintenance technicians, manufacturers, and DIY enthusiasts seeking efficiency, reliability, and convenience.
