Frequently Asked Questions
Q: What is a self-drilling screw (Tek screw)?
A self-drilling screw, often referred to as a Tek screw, features a built-in drill point at the tip. This unique design allows the screw to drill its own pilot hole, tap threads, and fasten materials securely in a single operation, eliminating the need for pre-drilling.
Q: What materials are these screws made of?
Our self-drilling screws are manufactured using high-grade Carbon Steel (C1022A) or Stainless Steel options, including SS304, SS410, and SS201, depending on your strength and corrosion resistance requirements.
Q: What surface finishes do you offer for corrosion protection?
We provide multiple surface coating options to enhance durability in harsh environments, including Zinc Plated (available in Blue, Yellow, or White), Ruspert Coating, Black Oxide, and Epoxy Coating.
Q: Can I customize the sizes and specifications?
Yes, custom specifications are fully supported. Our standard size range includes diameters from M3.5 to M6.3 (or #6 to #14) and lengths from 13mm up to 150mm. We can also customize head types, drive styles, and thread configurations.
