Premium Material Selection: We use high-quality carbon steel (Grades 4.8, 8.8, 10.9, 12.9), A2/A4 (304/316) stainless steel, and brass. This ensures optimal strength, durability, and corrosion resistance for any environment, from standard industrial use to harsh marine conditions.
• Full Compliance & Precision: Every threaded rod conforms to DIN 975 specifications, guaranteeing consistent thread pitch, diameter, and dimensional accuracy. This results in seamless compatibility with standard nuts and other fasteners.
• Exceptional Strength & Durability: Our high-tensile grades (10.9 and 12.9) provide outstanding load-bearing capacity, making them ideal for critical structural applications, tensioning systems, and heavy-duty anchoring.
• Versatile Surface Finishes: Available in self-color (plain), black oxide, hot-dip galvanized (HDG), and electro-zinc plated finishes. These options provide enhanced protection against rust and corrosion, extending the product's service life in outdoor or chemically aggressive environments.
• Wide Size Range: We stock a vast inventory from M3 to M56 diameters and standard lengths from 1 meter to 4 meters. Custom lengths and diameters can be produced upon request to meet your exact needs.

The GB845 Self Tapping Screw is ideal for construction and carpentry projects, particularly drywall installations where pre-drilling isn't feasible. Its corrosion resistance makes it suitable for both indoor and outdoor applications. The product meets multiple international standards and is available in various packaging options with flexible order quantities starting from 50,000 units.

Wafer Head Drilling Thread Cutting Screws are mainly used for the rapid fixation of metal plates such as color steel tiles and ventilation ducts, as well as the installation of outdoor facilities such as sun rooms, aluminum alloy window fences, and roofs at home.

Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.

The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.

The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
