Frequently Asked Questions
What is the difference between a self-drilling screw and a self-tapping screw?
Self-drilling screws (also known as Tek screws) feature a built-in drill point at the tip that allows them to drill their own holes in metal or wood without requiring a pre-drilled pilot hole. Self-tapping screws require a pre-drilled hole but tap their own threads as they are driven in.
What materials are available for your self-drilling screws?
We offer self-drilling screws manufactured from high-quality Carbon Steel (C1022A) as well as various grades of Stainless Steel, including SS304, SS410, and SS201, to meet different strength and corrosion resistance requirements.
Do you offer customized head types and sizes?
Yes, we provide a wide range of head styles including Hex Washer, Pan, Flat Countersunk, Truss, and Button heads with multiple drive options (Phillips, Hex, Torx, Square). Customized dimensions and specifications are also fully supported.
How do you ensure the corrosion resistance of the screws?
Our screws can be finished with various protective coatings depending on your application environment. Options include standard Zinc Plating (Blue, Yellow, White), Ruspert Coating, Black Oxide, and Epoxy Coating for enhanced durability in harsh conditions.
What is the standard lead time and shipping port for orders?
Our typical production lead time ranges from 7 to 25 days, depending on the order size and specific customization requirements. All orders are standardly shipped from the Port of Tianjin, China.
Can these screws be used for waterproof applications?
Yes. For outdoor roofing, cladding, and other moisture-exposed installations, we can equip the self-drilling screws with optional EPDM washers to create a tight, waterproof seal and prevent leaks.
