Frequently Asked Questions
We utilize advanced surface treatment technology that creates a denser protective layer, providing 5 times the anti-corrosion and weather resistance compared to ordinary galvanized products.
Yes, thanks to German technology and high-strength steel, these screws are designed for fast tapping and strong anchoring force in various metal parts.
The deepened design ensures a more secure fit for the screwdriver bit, significantly reducing the risk of slipping or stripping the head during installation.
They are primarily used in the manufacturing of doors, windows, interior decoration, and specialized connections between metal components where a flush surface is required.
Absolutely. We source raw materials exclusively from large, reputable steel companies to ensure every bolt meets stringent high-strength industrial requirements.
No, these are self-drilling screws. The integrated drilling point allows them to pierce through metal and tap their own thread in one single operation.
