Frequently Asked Questions
What is the difference between Self-Drilling Screws and Tek Screws?
Self-drilling screws, also commonly referred to as Tek screws or drill point screws, feature a built-in drill point at the tip. This design allows them to drill their own pilot holes and tap their own threads in a single operation, eliminating the need for pre-drilling.
What materials and grades are available for your screws?
We manufacture screws in Carbon Steel (C1022A) and Stainless Steel, including SS304, SS410, and SS201 grades, to meet various durability and corrosion resistance requirements.
Can I customize the sizes and surface finishes?
Yes. We offer diameters ranging from M3.5 to M6.3 (or #6 to #14) and lengths from 13mm to 150mm. Available surface finishes include Zinc Plated (Blue, Yellow, White), Ruspert Coated, Black Oxide, and Epoxy Coating. Custom specifications are welcome.
What are the typical packaging options and delivery lead times?
Our standard packaging options include bulk cartons, color boxes, plastic containers, and custom labeling. The typical lead time is 7 to 25 days, depending on the order specifications and quantity. All products are shipped from Tianjin Port, China.
Are these screws suitable for waterproof applications?
Yes, our self-drilling screws can be supplied with optional EPDM washers which provide an effective, waterproof seal ideal for roofing, cladding, and outdoor installations.
