Frequently Asked Questions
What is the main difference between self-drilling screws and self-tapping screws?
Self-drilling screws feature a built-in drill point at the tip, allowing them to drill their own pilot hole and tap threads in a single operation. Self-tapping screws tap their own threads but typically require a pre-drilled pilot hole.
What materials are Hebei Chudu self-drilling screws made from?
We offer carbon steel (such as C1022 hardened steel) and stainless steel options (such as SS410 and SS304) to meet different environment and strength requirements.
Do you support customized surface treatments?
Yes, we support a wide range of surface treatments including zinc plating (white, yellow, black), Dacromet coating, mechanical galvanizing, and epoxy painting for colored heads to match specific siding or roofing colors.
What is your typical packaging configuration and delivery time?
Our standard packaging is 100, 200, or 500 pieces per box/bag, packed in outer cartons and pallets. We also accept OEM packaging. Delivery typically takes 10 to 20 days depending on the order quantity.
Where are the screws shipped from?
All our products are manufactured and shipped directly from the Tianjin Port in China, ensuring fast and efficient global logistics.
