Compliant with DIN7985 standard, these stainless steel machine screws feature a Phillips cross recessed head, designed for reliable performance in industrial and mechanical applications. Crafted from high-quality stainless steel (304 or 316 optional), the screws offer exceptional corrosion resistance, rust prevention, and durability—making them suitable for both indoor and outdoor use, even in humid or mild chemical environments. The precision-engineered threads ensure tight, secure fastening, while the Phillips cross recessed head allows for easy installation and removal with standard Phillips screwdrivers or power tools, reducing slippage and improving work efficiency. With consistent dimensions and strict quality control, these screws guarantee compatibility with standard nuts, washers, and pre-tapped holes, ensuring stable assembly results.
Ideal for a wide range of scenarios, these machine screws are primarily used in mechanical manufacturing (e.g., machinery parts, gearboxes, pumps), electronic equipment (appliances, instrumentation), automotive components (lightweight assemblies, interior parts), industrial equipment (conveyor systems, production lines), and precision engineering projects. They also excel in furniture assembly, hardware fixtures, and renovation work that requires long-term reliability and corrosion resistance. Whether for professional manufacturers, maintenance teams, or DIY enthusiasts, these DIN7985-compliant stainless steel screws combine versatility, durability, and ease of use to meet diverse assembly needs.
